jeep5.9litre Posted March 24, 2007 Share Posted March 24, 2007 89 GL with the 3AT pushbutton 4WD seems to be having some issues. Car takes a few seconds to engage in any gear, once it engages car still does not want to move once the accelerator pedal is pushed. The car will move but not like it should. I guess with having 190k I cant expect much more from this tranny. I just dont want to give it up because it still runs great and for a Northeast GL the body has been holding up well. Anyone know of a fix? Quote Link to comment Share on other sites More sharing options...

daeron Posted March 24, 2007 Share Posted March 24, 2007 by all means, swap a five speed of some sort in there rather than scrap the car.. a tranny swap isnt THAT complicated. If you don't want to do it, someone else will. Quote Link to comment Share on other sites More sharing options...
jeep5.9litre Posted March 24, 2007 Author Share Posted March 24, 2007 Well, Id love to do the swap. I just don't have the time to go about doing it. I know I can defintely do it at my shop, but time can be an issue, along with getting the tranny and various parts needed. Quote Link to comment Share on other sites More sharing options...
Skip Posted March 24, 2007 Share Posted March 24, 2007 1) get the fluid changed via a flush sounds like the hyd. pump is not making the trip. 2) maybe add some Lucas Tranny honey in hopes of swelling the seals. 3) clean the govenor (see my art. in the USRM) it could be stuck in one of the higher gears. Does the fluid smell like gear oil? These transaxles, at this age, have a habit of loosing the seal between the diff and the tranny. fluids mixing => bad Ju Ju Quote Link to comment Share on other sites More sharing options...
jeep5.9litre Posted March 24, 2007 Author Share Posted March 24, 2007 Skip, I will try all of the above before I put serious consideration to the 5 spd D/R, but if I can get my hands on the tranny and components I will be going that route Quote Link to comment Share on other sites More sharing options...
hatchsub Posted March 24, 2007 Share Posted March 24, 2007 the 3AT is not a very good tranny. Mine had only 62,000 miles on it when i pulled it in favor of a 2wd 5 speed. The reason was that when cold it wouldnt want to upshift sometimes. When warm it was normal but it was just too annoying to drive. Try what Skip says and if that doesnt work go for a 5 speed D/R or hell even a good 4 speed D/R. Quote Link to comment Share on other sites More sharing options...

Try what Skip says and if that doesnt work go for a 5 speed D/R or hell even a good 4 speed D/R. whoa!! hold on, anyone realize he'll need to swap rearend as well and driveshaft? Auto=3.7 MT=3.9 with the exception of the 3.7 Turbo five speed(25 spline axles). So whatever you get, make sure you get a matching diff if you need it. Heck, even a single range trans would be fine. However if you like the auto, replacement ones are cheap. It is a simple trans easy to rebuild as well. You can''t beat the instant 4wd engagement of the hydro clutch either.

Numbchux Posted March 24, 2007 Share Posted March 24, 2007 1) get the fluid changed via a flush +75,000 fluid flushes can do WONDERS for older auto trannies. Quote Link to comment Share on other sites More sharing options...

The reason was that when cold it wouldnt want to upshift sometimes. Exactly what mine did, and exactly why I went for a manual. Quote Link to comment Share on other sites More sharing options...
