hi i have a cherokee 87 and it wont move in foward. before it was stuck in first gear , but then i kept using it around the ward and it slowly with time stop having power in first gear. now you have to like push the truck for it to move. works with full power in reverse tho. any sucjections? i realy want my tranny back . dont feel like changing it incase its not the problem.

its an automatic tranny btw.

thanks steph.

 

Fluid level is good? Other than that it sounds like your tranny's pooched

 

Are you saying it won't move forward at all or is it like it's trying to take off in 4th gear?

 

if it feels like its trying to move in 4th gear then the tcu which is located under the dash on the passenger side may have gone bad or thers no power going to the tcu.

 

i have a feeling its pooched . its like its in nutral but if you rev it at 3.5 rpm youll feel it trying to move. all the fluides are good . its just been changed. is it possible that its a sensor underneath my hood?

 

How does it do when you shift into low (shifter ALL the way back)?

Manually selecting low rules-out the transmission electrical controls.

Just change right before this problem started or a bit ago?..Have you checked it or are you just assuming it`s good because it just got changed?

 

How did the fluid that came out when you changed it look? If it was super dirty and nasty, changing it is probably what screwed the trans. If you let an automatic go for too long, when you change the fluid it frees up a lot of gunk that used to be stuck somewhere in the trans. Then that gunk flows through it and a trans that used to work will suddenly die.

 

fluid is and looks new , just checked it

 

X 2. Manually put your shifter into 1-2 and if your Jeep takes off normally, then select 3, then select OD. If it shifts through all of the forward gears like normal, manually, then, your TCU is either fried or not getting it's 12VDC to turn it on. The good news is if this is the case you can either fix a simple wire for nothing or you can pick a TCU up from a Jeep in a JY for a few bucks rather than replacing your whole transmission for MANY bucks.
