nobody has any clue wat this could be
my brother is jus scared to go up a bridge one day with traffic behind him and the transmission jus cuts out on him

Ok just putting it out there but if the problem only happens on inclines, try checking the actual fluid. Maybe the flui is low causing the trans to slip. Try checking it, the g have a dipstick, make sure car is on

fluid check sounds good.
also, lots of miles?
perhaps the valve body has something caught in it. If a check valve doesn't close, then it may not be properly shifting.

low miles
45k
fluid check sounds good ill check tomorrow

[shinobis13hb]

yea check the fluid te torque converter is problly going to crap. but im not up to date with the g

[irax]

45k miles is about when the fluid is changed and the filter too

G35's are like blonde bombshells....expensive , unreliable and loose lol.

But in my personal XP with them any little thing cause's a huge problem. If he has been racing the car that could be the problem, not that on 45k in an auto he woulda messed anything up BUT the ECU from the factory has basicly a ANTI race chip in it. If you drive like a bat outa hell for a long period of time the car will basicly as you said put itself in limp mode. The only way to fix this is go to your dealer , and when you do that they void your waranty :). Trust me.

Which later leads to a 06' Supercharged g35...since you dont have a waranty anyways...:)
