I have a '94 Jeep Grand Cherokee, inline 6, automatic. When I start to accelerate, whether moving through a stop sign, etc, it's getting stuck in 1st gear and I have to release the gas pedal and sometimes tap on the brake to get it to go to second. It drives fine when I'm the freeway though. This doesn't happen all the time, however, last night it would not move to the next gear.
I also had the transmission serviced almost 2 years ago but it was sitting and I started driving it about 6 months ago. I also noticed there was too much transmission fluid. Would this cause the problem?
I did the key thing, it brought up code 12, which was something about the battery.
I'm not that knowledgeable with cars. Does anybody have any ideas?
so it hits redline and won't shift? Or does it shift after a certain RPM? Something sounds like its stuck in there.
Usually too much of a fluid is a bad thing...if there's way too much tranny fluid chances are whoever serviced it wasn't too bright...i would drain and refill the tranny to the proper level at the very least, paying close attention to the condition of the fluid (see if it smells burnt or looks cloudy or has metal fragments in it) or get it looked at by someone else. The last thing you want is a busted tranny that could have been fixed earlier.

I drained the transmission fluid and replaced the filter. It was running great for a while. Now, for some reason, its accelerating very slow whenever I'm passing through a stop light. Sometimes, it starts rumbling if I accelerate too hard since it's slow already and I have to pull over and turn it off. Once I am at a higher speed, it runs fine. Again, there is no codes. Yesterday, I was backing out of the driveway and it completely stop.
that's "limp" mode. you are not downshifting to 1st or 2nd and are constantly in 3rd.
with no codes that's probably mechanical as opposed to the gov pressure solenoid and sensor not having power or working.
sounds like rebuild time. but drop the pan and see what you find in it.
oh yeah, check the fluid level; hot, running, in neutral.
'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
Please dont be insulted, but what type of tranny fluid did you put in it?
It needs ATF +2 or better. If you put dexron in it.....that's your problem. (Dont laugh, either, cuz I've heard of tranny shops doing it.)
I'm not insulted. I used valvoline AFT +4 after I drained the fluid, and checked the fluid when it was hot, neutral, its fine. I did find Dexron in the back area of the Jeep from the previous owner. Could that be a problem, which then I do a flush?
I've read that some people got a rebuilt and it was still stuck in "limp mode". Should I try replacing the gov pressure solenoid and sensor?
Might not be related to your issue....but it's something to think about. A couple of times, my 97 model wouldnt downshift all the way to first gear after I drove through some deep water during a very heavy rain here in town. The next morning it was fine....so I just assumed a connector became wet and it acted stupid...but maybe there is more to it than that.
