Gears do not 'slip'.

To check the fluid level on the mt you have to jack the car up front and rear so it's level and remove the fill plug (upper one) on the transmission. If fluid trickles out it is full. The procedure for filling is to add mt fluid until it begins trickling out of the fill plug and cap it off.

What is it you are afraid of risking? Aside from wasting money?

You have a manual transmission, which means if it slips internally, it's totally destroyed.

See if you can pull the release fork a bit by hand. If the master is releasing pressure properly, when the pedal's up you should be able to push the slave in a little bit with a few pounds of force, one hand.

Otherwise, it sounds like you haven't worn your new clutch in - new clutches often don't fully engage or disengage until you've let it slip some, but don't overheat it - this is why they talk about a "gentle" break in period - don't just sit and smoke it, but let it slip plenty when you take off, in between plenty of cool-down time.

Do you smell it?

You did a clutch but never changed the tranny fluid?

Maybe your clutch pedal isnt adjusted properly. Too tight and the clutch will slip. You could also have poor throwout bearing tolerances.

Late reply

Sorry for the late reply. I've been pretty busy.

I got around to adding new gear oil. It took quite a bit too fill so it probably was low. But it didn't do anything to help the problem.
Eventually I ended up replacing the transmission. This was mostly due to the car no longer shifting into reverse, and having trouble shifting into other gears. While it fixed the shifting problem it only partially fixed the slipping. But at least it seems to have helped some. It still slips a little but not nearly as much. It might just need a new clutch now, I'm not sure.

I should have replaced the clutch while I was changing transmissions but I got impatient since I would have to wait a while to resurface the flywheel. I figured it would be fine with its current one since it was relatively new. Unfortunately I have to put this problem on hold for the time being since now the car is having other issues with overheating.

I just wanted to thank everyone who gave me advice on this. If your interested in helping me figure out my latest issue, here is a link to my new thread

Coming from someone who has had tons of clutch issues....

It's definitely a clutch problem.. not brakes... not transmission fluid

First, the clutch needs to be bled, you said that you didn't do that, Idk if you've done it since.

Second, where is your pedal engagement/disengagement point? Is it high? If it's too high then your clutch is not completely engaging. I'd bet money that this is the problem.

I did bleed the clutch. Did not help unfortunately. And my engagement point isn't very high, it got lower when I changed the clutch.

You need to readjust the pedal every time you change the clutch. I have a feeling youve been setting it too agressively. There should be a tiny bit of slop where youre just pushing against the return spring on the pedal before you feel pressure from the clutch. If theres no slop that means the clutch bearing is disengaging the clutch by preloading the springs and weakening the friction between clutch and flywheel, eventually making it slip. Too much slop and the clutch wont disengage and itll be hard to pop out of gear
