Automatic transmission is dying...

hi guys,

iŽve a 1996 zj with the 44re transmission in with about 200k miles on it and the following problem:


the misery started one year ago with suddenly decoupled transmission on highway.

i drove about 80mph and without any warning the transmission shifted to "N" -> shift lever still stands on "D"...

the oil level was correct, the oil color and smell was ok too, not burned..

back then i helped to shift to "N" and back to "D" an i could drive along.

Now this problem happend at every longer trip and it doesnŽt help anymore to shift -> iŽve to drive right to the street, stop the car, shut off the engine and restart it (sometimes it works again normal at the first try, sometimes it needs more restarts)

Does anyone have an idea what it could be? IŽm thankful for every input/idea.

IŽve my own garage, so if it necessary to change all switches/solenoids, there will be no problem to do it on my own...

bye,
samse

When was the last time you dropped the pan and changed your fluid/filter? You might want to see if there is any significant debris in the pan or stuck to the filter. Sometimes things wear to the point of disintegrating, and other times they break, leaving telltale pieces in the pan.

Do you have the Factory Service Manual for your year ZJ? If not, you might want to get one and check the transmission troubleshooting section. It might have something to say about your symptoms.

200K miles isn't a bad run on an auto transmission attached to a V8. Good luck.

They are the transmission's internal pressure switches, solenoid, etc. While I don't think they'll fix the OP's issue, I wish him luck. Hopefully, he'll report back when they are installed, and the ZJ's back on the road for a test drive.

check your shift cable at all points.

check the shift cable bracket -- on the transmission -- that it is tight

check shift cable adjustment -- it should start in N and P and NOT start in any other gear

see my thread: http://www.jeepforum.com/forum/f13/4...ading-3752521/

Hi guys,

like everytime with my jeep -> since iŽve written the thread the transmission works fine....

However today iŽll change the ordered parts and iŽll watch an report if the problem comes again or not.

@ paulsheer2: thx for the tip with the shift cable, iŽll check it today too, the engine starts only in "N" an "P", so this works normal.

good link, havenŽt found it on my own...

bye,
samse
