Transmission Rebuild question

[Chris_518]

I had searched for this info and couldn’t really found anything that was helpful so I decided to make this thread to show people the information they need and to answer any questions people may have. I have looked on the internet for a rebuild kit and didn’t find much, until I found Drivtrain.com, that’s where I got my kit from. I called them up and asked some questions about the kit and they were very helpful.

When rebuilding your transmission I highly recommend getting the disassembly instructions found in the Factory Service Manuals (they can be found here, www.240SXTECHDVDS.org Factory Service Manuals Page (http://www.240sxtechdvds.org/FSMs.html)). If you don’t have any access to specialty tools then you will either need to buy some or find someone who does. Specialty tools you’ll need are a press, gear puller, and a bearing separator

Also another note, when you’re dissembling it do not let the Synchro Hub and Sleeve separate, they have been connected together for who knows how many miles and they have “married together” they should be put back in the same way they were taking out. A good way to make sure about that is to mark both parts so you can line them up in case they do separate

I wasn’t able to get pictures of all the dissembley since I was doing it in class and was on a schedule

While you have your transmission casing apart and if its dirty and you want to clean it up, now is the best time. Since I had mine apart I cleaned it in a part washer that we had at school. Once it was cleaned up as best as I could get it I painted it. If you paint yours make sure you use tape to tape up holes you don’t want paint getting into. I used less then1 can of silver spray paint and less than 1 can of clear coat, and to make it easier I used the adapter to make the spray can like a paint gun (I will get pictures of this later)

I haven't been able to take a picture of it after the rebuild but I'm gonna try to take a picture tomorrow


***If you go to your local dealer their prices may be different, and also make sure you have your VIN with you. When I went the parts guy wanted to know the VIN so he was sure that he was selling me the parts I need, even though the parts aren't VIN specific***

[jr_ss]

Contact your local transmission shop, a reputable shop should be able to sort it out for you.

I had the same problem trying to find synchros and bearings for my 300zx trans, but the local transmission shop came through and got everything needed for me.

[Pacman]

I can't find the rebuild kit paperwork that I got when I rebuilt my transmission a couple months ago but I do know that I used the standard kit (not the 31mm needle bearing), and was the two-piece 2nd gear synchronizer. When I did mine, I found that the 2nd gear hub/sleeve was worn as was the shift insert broken. Make sure you check all that. I went ahead and replaced all the hub/sleeves, inserts, synchros, bearings, seals, plugs, main/counter shaft nuts, and insert springs. It shifts factory brand new.

Now, you do have access to a press and a wrench that's sized 1-1/8" and 24mm, I believe? You'll need a press, too. I had to heat up the brass sleeve on the main shaft for hub 3/4, I think it was. Got stuck on after 191K miles. Don't forget, when you get the go to take off the nut on the main shaft, lock the transmission in two gears. I used the two that were at the intermediate plate.

Good luck and have fun. Post if there are any questions.

Oh man sounds like you had a good experience with it. Are you still in NorCal? If so where, would you be interested in doing the work?

any update. How did the rebuild go?

[nightsauce]

in for an update as well

[Chris_518]

Didn't know people were still looking at this.

As for an update, we got the transmission put back together correctly. Everything in the rebuild kit i bought was the correct sizes and fit perfectly. I will post up pictures when i am home from school. It hasn't made it in the car but we were able to test it when it was finished and i was able to shift into all gears with no problem.

I have been unable to put it int my car yet because i had gotten into an accident so it pushed back the install of the transmission. I'm hoping that when the beginning for spring comes around that ill be able to put it in. It might get held back a lil longer if i decide to rebuild my engine while at school too.

[slider2828]

Would these parts work for an SR20 Redtop Transmission? I wonder how would I go about finding the parts for rebuild?

[Chris_518]

I don't see why it wouldn't work, as far as i know the KA/SR/CA transmissions are the same Internally except for the bell housings and i believe the CA transmission has a different 5th gear ratio

[WIKID S4TEEN]

A lot of good info on here. Thanks for the thread.
I'm having my tranny rebuild too. But I didn't have the guts to rebuild myself.
What kind of paint is that and did you primer it first?
I'm thinking of replacing all the sensors too. Except the speed sensor, cuz it's kinda new.

[rastaman]

very nice i will need to do this soon...

No problem, i figured since I've seen people ask about rebuilding their transmissions and not get any answers and since I was rebuilding mine that i would post this. Ideally i would like to clean it up so its easier to read instead looking at 3 different post for information (I may do that some time).

I got the paint from Advanced auto, I dont remember off hand what kind of paint it was but I have it in my garage and will post up what it was when im home from work, and no i didn't prime it. I cleaned it up as best as i could then when it dried i spray painted it. I started out lightly covering it and did a few layers like that then i sprayed right to left and starting putting more on it in even coats. I am reusing the sensors, I looked them over and they all look to be in good working condition.

[slider2828]

Have you rebuilt tranny's before? How hard would it be to do it yourself?

[Chris_518]

Have you rebuilt tranny's before? How hard would it be to do it yourself?

No I haven't, this was my first time rebuilding one. Too be honest its not that hard, just gotta follow disassemble instructions and you'll be able to get through it (Don't know what you have access to but I highly recommend using the one from the FSM, as alldata skips some steps), and make sure you keep everything organized, in order, and don't let the sychro hubs and sleeves seperate. Only thing is you'll need a press for some of the bearing.

[KiLLeR2001]

I'm planning on buying the rebuild kit and taking it to a transmission shop for rebuild and have them only charge me labor.

[ze12o]

Thanks for the info. wish you were closer would of paid you to do mine.

thanks bb4_96. i guess ill just take it from my spare s13 tranny. now do i have to take my whole tranny down? or can i just take the tail end off and work from there? sorry so noob.

Off topic but TranStar is a very good reputable company, their facility is just minutes from my house. Kinda nice to see some people here using their rebuild kits!

[Chris_518]

You have to remove the shifter, striking arm and the back housing. Then there is a snap ring that holds it in place that needs to be removed to take out the speed gear

Off topic but TranStar is a very good reputable company, their facility is just minutes from my house. Kinda nice to see some people here using their rebuild kits!

The quality of the parts was awsome and the bearings had the same numbers as the OEM Nissan ones so there was no confusion on which bearing went where. I definitely recommend their kit if rebuilding your transmission, and I will definitely go with their kit if I ever rebuild more transmissions.

[lilpiton]

very good info on here. anyone know which is a better rebuild kit to go with?

[Chris_518]

very good info on here. anyone know which is a better rebuild kit to go with?

What do you mean which is a better rebuild kit to go with? Theres only 1 kit talked about in this thread. Just go with this one, qaulity of parts is great and the part numbers pretty much match the OEM part numbers. Just go with the kit I used.

[I WE TODD ED]

Great info

[splitfire]

One question:
Will DTS-BK133CWS rebuild kit fit to JDM S14 Zenki transmission?

[SuperBlackS14]

As far as I know, which I would deff double check before you pull the trigger, the SR and KA gear-boxes are the same. Gear-ratios, Synchros, ect... Same deal. Bell-housings were different for sure.

Again, I make no claim as to the guaranteed truth of that statement, and double check... You know search... This is a thread about how to rebuild a transmission, and I doubt OP knows for sure if the kit in question will fit, but I would look up the gearbox part numbers from Nissan, either in a forum database or from Nissan specifically. If they match, hey, the rebuild kits probably work in both.

[J90lude]

I'm loving this thread already.

[Chris_518]

People still look at this, damn. Information about the transmissions is out there. As I recall the S13 and S14 transmissions for the KA and SR are the same exact for the bell housings. The gear ratios are the same and the back housings are the same so I don't see why it won't work for your transmission. Im not saying I'm positive that it will work.

[sleepyS14se]

did you do this on a s13 or 14 trans? yes i know they are the same.

is the kit the same for s13 and 14?

[sleepyS14se]

what is up with the kit listed below the s14 listing? It is like 271.

I did a quick look for those synchros and I haven't found anything. I'm not sure if they make them, only reason I say that is because they would have them for the KA transmission since they are the same internally. so with that being said, the rebuild kits will be the same.

excellent i needed this

glad it can help ya out. if you have any questions don't hesitate to ask.

Commenting to come back to later.

[Kingtal0n]

Im doing this soon. I was hoping you could tell me which "specialty tools" I will definitely need to buy. The FSM lists 14 different tools for the job.

I see for example it looks like you did without the
"ST23810001 adapter setting plate"
I can't even find someone who sells it either, nobody will take the ST part number. It must not be that important?


Updates:
Looks like I will need to buy a 20 ton press (harbor freight: $200) to be able to comfortably do this job in the backyard? Any comment?
I am really curious how a press can used to "separate" the parts. I've never used a real press before (we have one in the inorganic chemistry lab used to create transparent crystal discs for use in the Infrared detection machine but that hardly counts)

I never used any special tools. Just basic hand tools and a hydraulic press that we had at school. YouTube does wonders to explain how tools work.

Something very odd about your thread. You start off with a couple pics of the trans pulled out of the case- and then that is all, it ends there. Kinda sketchy how you simply "bypassed" every single trans picture of the actual rebuild, you claimed " you are on a schedule ".

So, lets say I buy that, you were on a schedule and couldn't take a single picture of the rebuild process. Fine. You claim this thread is for "helping" us to rebuild our transmissions- yet you make absolutely NO mention of the fact you had purchased the incorrect rebuild kit, and that it was missing 2 critical synchro ring parts. Yes, I bought the same kit, actually I bought one of each kit from that exact site- just in case- and discovered this myself when performing the rebuild.

What I think really happened is, you let someone else rebuild the transmission, and they never mentioned the missing rings to you and simply reused the old rings (probably without telling you) and they never took any pictures. You also failed to mention the other inconsistencies in the FSM about the rebuild process, such as the sleeve orientation misprint which shows the groove facing 4th when every SR trans I took apart has it facing 3rd.

If you actually want to help people, you have to start by being honest. You didn't rebuild that trans, either that or, you are misleading everyone deliberately into buying the wrong kit. To all people reading this thread: the kit he posted, and the other kit on that website, are for the KA transmission, not the SR transmission, which yes, is different with respect to two of it's synchro rings ("baulk rings"). I've taken apart all kinds of SR transmissions, both versions, with synchro reverse and non synchro reverse, from 92's and 98's, and type-X, and none of them match up to the KA rebuild kit exactly.

First off I never said this thread was going to be a how to. This was more so to give people a record of where they can find a rebuild kit and what extra parts are/may be needed, where to find the information on how to rebuild the transmission, and have the OEM part numbers for the parts.

I rebuilt this at school, hence being on a schedule (It was a 3 hour class with only 2 hours of actual working and we didn't have this class every day of the week). Since I was rebuilding this at school my teacher (who was a little bit of a dick) was more interested in us working on it and not taking breaks every couple of minutes to take a picture of every step we did, and because the FSM clearly showed the steps to take. (I will double check my external hard drive when I get done with work and drill tonight to see if I have any other pictures).

I didn't buy the incorrect rebuild kit. Everything that is needed is in that rebuild kit, except for the two lock nuts, and the shifter plate gasket (as noted). The only difference between the two rebuild kits the company sells for the transmission is one has a larger needle bearing (as seen below which is a direct copy from the website)

"FS5W71H 5spd, RWD
240SX 4 cyl 2.4L 1988-93 Aluminum cases, rear load DTS-BK133 $131.98 DTS-BK133BWS $179.10
240SX 4 cyl 2.4L 1993-97 Aluminum cases, rear load DTS-BK133 $131.98 DTS-BK133CWS $165.98
240SX 4 cyl 2.4L 1993-97 Aluminum cases, rear load - 31 .25mm O.D. large pocket needle bearing DTS-BK133E $140.66 DTS-BK133FWS $271.32"

Again, no one built the transmission but myself. There were no inconsistencies because I used the correct FSM.

There's your issue right there. Yes this rebuild was for a KA Transmission (it was originally posted in the main post but apparently got removed when i updated it at one point in time), but if you read through this thread you would have seen multiple posts stating that no one was absolutely sure if this kit would work on a SR. (see exapmles below)

I don't see why it wouldn't work, as far as i know the KA/SR/CA transmissions are the same Internally except for the bell housings and i believe the CA transmission has a different 5th gear ratio

One question:

Then we get to your first comment on the tread.

No where in here do you ask "will this work for an SR transmission, you just assumed it was. I know it doesn’t say “KA Transmission” but the thread definitely doesn’t say “This is for a SR Transmission”. If you asked that, I would have told you that I'm not sure and to look further into it.

So before you jump to conclusions you should take your time to get your information correct (read the full thread, it's only 2 pages) before you try accusing me of being dishonest and trying to mislead people.

[collegekid]

Chris_518 can you comment on how much power your car makes, how you drive, etc?
Has rebuilding the Ka/Sr/CA transmission been worth it in respect to what purpose your car serves or do you recommend people to just buy a z32 or z33 transmission and swap those in?

Do you have any other recommendations on what other things would help, such as any tips or tricks for a first timer attempting this?
An example of this is where you said
"Also another note, when you’re dissembling it do not let the Synchro Hub and Sleeve separate, they have been connected together for who knows how many miles and they have “married together” they should be put back in the same way they were taking out. A good way to make sure about that is to mark both parts so you can line them up in case they do separate"

Do you have any other tips like that?

okay so has anybody been able to confirm which kit would work for s14 sr trans? trying to follow this up as I will be attempting to rebuild my spare trans

[s14unimog]

I've rebuilt my S13 SR transmission with an aftermarket kit pulled for an S13 240sx. I can confirm that the parts are the same. Rebuilding an SR trans will go a long way for reliability from what I've found. My car makes just over 400whp (340ish TQ) and the rebuild has held up to both road racing and drifting with a 6-puck sprung clutch and 245's for about 3 years now. Granted, I've never grenaded one, but I've trashed syncros and dealt with other issues. For what it's worth though, there are special tools required, but you don't need to purchase the ones from the FSM (if you could). The main shaft nut has to be torqued and cannot be done with a traditional socket. There is also some tricky setup required to press the necessary bearings on and off the main shaft - not to mention reinstalling the shaft assemblies into the center plate simultaneously. It's not a "difficult" task but takes time, patience and close attention to detail (especially when reinstalling the check balls for the shift rails or the inserts/clips at each shift collar). There are a lot of parts and a very specific order to installing everything. PAY ATTENTION THE WHOLE WAY THROUGH!

Tip: When reinstalling a new bearing, place it atop a lite incandescent bulb and allow it to heat up. They'll slide right on once they expand. Makes reassembling a breeze.

Tip2: NEVER press against the side of a gear, you will chip it. Helical gears often have small burrs on the edges of their teeth that create a "high spot" on the surface you're pressing against - localizing the force there. If you do chip a gear, it's usually okay just so long as it has not chipped too far out into the pattern (they run in the middle obviously). I've chipped one in my Jeep and it's still in service, so it's not likely you'll trash it. A good way to prevent it is to sandwich a softer metal (brass, aluminum, etc...) under it so the burr can dig down into it without stressing the gear.

What you should end up with when you're done... Notice that one of the bearings is cut up. That's b/c I couldn't find a way to fixture it in my press and it wasn't possible to get a bearing press plate in there.

What 3/4 gear hub w/syncros looks like off the shaft (5th/rev. is disassembled in the background). It's a good idea to keep as much of this stuff assembled as you pull things apart. That collar in the middle sliding up/down (in this picture), normallly forward/back, crossing the teeth on the yellow syncro and finally over onto the gear hub is what you hear grinding when you "grind your gears". It's important to inspect these teeth on the hub. If you've neglected this repair for some time, damage will be on those gear hub teeth too.

What about the Baulk rings that Kingtalon was talking about? Did it straight up work or you resused them off the old tranny?

Its been a while since I have been on this site so I apologize for the long delay. I found some pictures a while back but never got a chance to upload them so I will do that tonight.

At the time I did this, I had also rebuilt the motor (bored 20 over, with forged pistons and forged rods, all new bearings, ARP head studs and main studs, refreshed the cylinder head) so i would imagine it wasnt too much more then the stock HP rating. I didn't drive to crazy, I drifted it once in an open parking lot for all of 5 minutes, and I did a decent amount of pulls with it (Never got a chance to bring it to a track, so idk how much faster it got after the rebuilds). For how I drove it, the rebuild of the KA trans was plenty, however I have no experience with the Z32 or Z33 transmission swaps, so i can not speak of which is a better route for someone to go.

As for tips, just take your time and be as neat and organized as you possibly can. You will find that putting everything back together goes much easier if you're organized.

As stated in other posts the kit I purchased and showed worked perfect for my transmission and the kit WAS NOT missing any Synchro Rings. When I finished rebuilding my transmission it had all new synchro rings. He was rebuilding a different transmission then I rebuilt and did not confirm that that the parts were compatible before purchasing.
