whoopingbob5 Posted January 20, 2009 Posted January 20, 2009 hey guys ever since i first saw a comanche i have wanted one....well i got one 1986 ($250) with a bad ax5 transmission...its got the 2.8 V6 and a 5 speed 2wd...the motor runs as well as one could expect for 22 year old motor...i need to get this truck moving so here are my questions.... will the tranny from a 1991 2wd cherokee 5 spd manual fit in place of the tranny in my 86 comanche (its 2wd 5 speed also)...if not where can i find a tranny for it??? i lost all gears except 4...i was told that all of the gears run on a counter gear except 4th...when i drained the tranny almost no fluid came out...so i put some in and drainded that and there was some metal in that fluid...i filled it with synthetic in hopes that if it had fluid it would regain the lost gears...no such luck...i need some help.... also would the tranny from a 2.8lv6 s10 of the same year work??? thanks for all of the help
comanche13 Posted January 20, 2009 Posted January 20, 2009 talk to JeepcoMJ he seems to know alot about tranny's
BLHTAZ Posted January 20, 2009 Posted January 20, 2009 I am not real up on tranny interchangeability, but I do know that the one from the 1991 will not work. The S10 idea sounds feasable to me, but again...not sure.
Pete M Posted January 20, 2009 Posted January 20, 2009 If the 91 is a 2.5L, then yes. If it's a 4.0L, no. The 4.0 transmissions have a different bolt pattern Any AX-4 or AX-5 from behind any year 2.5L (or the older 2.8L) will work fine for you. car-part.com might be of some help. It's a search engine for junkyards. Be sure to search for multiple years of MJ or XJ since there cold be a part number change that limits off the search. Any year will work. :D --Pete
BLHTAZ Posted January 20, 2009 Posted January 20, 2009 So Pete, you are saying that the AX-5 from a 2.5L will bolt up to the 2.8L? I have never dealt with the smaller engines so I am trying to learn a little here too ;)
Pete M Posted January 20, 2009 Posted January 20, 2009 Yes, they share the same Chevy 60* block bolt pattern. :thumbsup:
bigd44889 Posted January 20, 2009 Posted January 20, 2009 ok pete so does that mean that the 700r behind a 2.8 chevy will bolt to a jeep 2.5?
Pete M Posted January 20, 2009 Posted January 20, 2009 In theory, yes. But when it comes to transmissions from Chevys, the CPS issue comes into play.
bigd44889 Posted January 20, 2009 Posted January 20, 2009 ok got my brain working now getting new hillbilly idea
