i think my tranny is done
I have a 2002 GLE with a 120k and the tranny has gone to hell!!!!!!
First I was getting hard 1-2 shifts which lasted a few days, then hard shifts and slipping going from 2-3, now it feels like its shifting out of 4th when taking off from a stop, and my reverse totally went out, im sure I left out a few other things it has been doing, its just been pissing me off so much
could this be a fluid problem, something electrical, or just plain old wear and tear??????

good question.. the answer and maintenance history could give us some insight into why it happened.. if you are the original owner, how did you care for the transmission... any regular fluid changes or flushes?

whats the TCM? and how do i know if its bad? I just picked up an 03 GLE, tranny fluid is dirty but i was debating on doing a flush (i have read that this can be deadly) or just replacing the fluid. tranny shifts perfectly right now.
sorry for the thread hijack! but i cant post questions yet.

yea i know i need 15+ posts, waiting till i get there.
How safe is a tranny flush on the maximas? i know on older acura's its not recommended as the dirt gets stuck on the screen and can cause premature failure.
my car is at 70k miles.

I read through the DIY section, but the threads seem to be mismatched with the subject. the tranny flush thread i read was linked to Ksport suspension review. lol

I hate tranny problems. On Supras, I know a lot of times it has to do with either a bad TPS or the kickdown cable adjustment has gone out of whack. Not sure if Maximas have a cable, or if it's electronically controlled.
Last thing I had to replace on my auto was the solenoids - I fortunately found someone online that gave me all 3 for just $25 from a used, low-mileage tranny he had laying around. From the dealer it would have been over $200 for just one of them, and there are three. My tranny was skipping 2nd or 3rd gear, runnin in"limp"mode. Maybe there is a diagnosis procedure from the Maxima factory repair manual - one of the other guys on here might be more familiar with it.

well im having it looked at right now by my buddy at nissan for free so cant go wrong there, hopefully its just a TCM, and didnt put any damage on the tranny while driving around the past few days

had tranny problems
nissan replaced tranny under warranty (but failed to replace TCM)
within a year, started having problems again
replaced TCM
never had the problem again.
realized that the original tranny actually went bad because of the TCM

TCM receives thousands of inputs. it compares all that with stored values. when it meets the values, it sends signal to solenoids which changes the gear.
when the TCM is bad, it has problems processing the inputs and delays the shifts.

When was the last time you had a drain and fill or a flush? Just trying to get a little base info so everybody can learn from this if it isn't TCM related.
If the fluid is not in brand new condition, then do a flush. The MYTH is that by doing a flush on a really old transmission, that it can remove gunk that is preventing leaks. But I believe this is a myth. You should always maintain your tranny fluid. Don't let this keep you from doing a flush. I've never read any real stories about a flush killing a tranny. You'll be fine, don't worry.

Yes the fluid is brown and does have a smell to it. The previous owner never had it flushed and I never got around to it.
Well the Nissan tech said it wasnt my TCM and wanted to perform other test, but I havent got a chance to take it back. I really just want to take it somewhere else and actually pay to have em check it out. My buddy didnt charge me anything so I dont know if they took the time to check it throughly as if I would paid them.
I really just find the hard shifting and slipping, and my reverse gear locking up something electrical. Well if worst comes to worst I can get a used tranny with under 50k for $550 and installed for another $300 plus cost of fluid and what not.

To the second poster, not the one with no reverse, mine had an output shaft speed sensor go out which was causing all kinds of crazy shifting and getting stuck in 2nd. Aamco said it needed to be rebuilt. I bought a code scanner and pulled the code - said Rev sensor. Replaced it (speed sensor) and have been good for the last 20K.
What did your code read?

Probably the clutch packs are going out. Typically, you only pop a code if there is an electrical/sensor/solenoid problem with the transmission. Try manually shifting at higher rpms on the 1-2 shift and see if that helps. That usually increases line pressure so the clutch packs will grab more quickly.

Solenoids control the transmission electronically, while each gear has a clutch pack that consists of clutches and steel rings that provided the clamping force in each gear (sort of like a clutch in a manual).
Here is a pretty good overview of how an automatic works and the parts they consist of.

I have the same problem, hard shifts 1-2 3 ok if manual shift o/d Shot to just rpm no speed increase, seems like no line pressure there. + no codes= I figure valve body ( boosted max BTW) waiting for vb mod to come back.

Yeah! I have an 02 max and mine is doing the same thing. 1-2 slow change. And I keep up very well on fluids. Had a recent flush this summer and had a check for winterization. I am going to look into the clutch packs.Hmmmm

does yours do it at high rpms, or during normal driving?
