Trans hard to shift after warmed up

[mczavala76]

Ok so here is one for you Jeep techs. i have an 88 comanche 4.0 with a ax15. and 231 transfer.

when I start to drive its fine. shifts into 1st, 2nd,3rd and so on.. after I run it for a while it starts to get harder and harder to shift back into 1st or 2nd gear. If I'm coming to a stop and slowly try to put it into 1st gear ( as long as I'm not at a complete stop it will go into gear) its when I come to a complete stop and go from N and then try to go into 1st or 2nd it won't go in. i have to force it.I tried changing the fluid 10w30. It only does it after its warmed up. I'm thinking its in the transmission. but not 100% sure. let me know what you guys think.

:hmm: I had the same problem when my clutch slave cylinder went bad in my 86XJ

 

and then again in my 90MJ when the master clutch cylinder went bad.

Well Ill give that a try. It was replaced not too long ago maybe 6 months. but then again in this industry it doesnt mean its good.

Mine does this too and i bled the clutch and that helped a little but i have alot of play in my clutch pedal...the bushing all the way to the left for the rod is shot... see if yours has some play :dunno:

Did you swap the trans, because the AX 15 didnt come out till late 89

No The clutch pedal has no play at all. the pedal feels fine. Ill try to bleed the system and go from there. and yes the transmission was replaced with an ax15. I bought the truck that way.I'm finding alot more upgrades on this truck as i work on it.
