mnkyboy Posted February 1, 2013 Share Posted February 1, 2013 The clocking of the t-case will be a little different but it should fit. Link to comment Share on other sites More sharing options...
88mj2.5 Posted February 1, 2013 Author Share Posted February 1, 2013 So the bell housing will bolt up to the back of the block? And i don't think that would make to much of an issue slightly different drive shaft angles? Link to comment Share on other sites More sharing options...
Bounty Hunter Posted February 1, 2013 Share Posted February 1, 2013 Yes, they'll bolt up, but the front output side of the transfer case will be closer to the tub than if using a XJ/MJ transmission. There may be fitment issues here. Link to comment Share on other sites More sharing options...
Geonovast Posted February 1, 2013 Share Posted February 1, 2013 5th gear won't be much use to you. The 2.5 tends to dog pretty bad in 5th with 3.55 axles. I did the same thing with an MPFI 2.5, and didn't even bother with 5th unless I was doing more than 70 on level ground. You can still use the trans obviously, for the 4wd conversion, but if you rely on 5th a lot, your mileage is probably going to go down. Just something to keep in mind.

Bounty Hunter Posted February 1, 2013 Share Posted February 1, 2013 He's right, forgot the 2.5L 4spd was plagued with 3.55 gears, despite my MJ having the same setup LOL. Link to comment Share on other sites More sharing options...
88mj2.5 Posted February 1, 2013 Author Share Posted February 1, 2013 Hmm thats good to know the front axle i am looking to get has 3.55s i was gonna jack the back up to check before i buy it and could tail shafts be swaped to make the 4 speed work? And thats shocking never knew that with 5th gear I'm still pretty new to the mj world lol Link to comment Share on other sites More sharing options...
88mj2.5 Posted February 1, 2013 Author Share Posted February 1, 2013 A front axle * Link to comment Share on other sites More sharing options...
Bounty Hunter Posted February 1, 2013 Share Posted February 1, 2013 No. You can use the 5spd, just don't plan on using 5th gear unless you gear the axles lower. Link to comment Share on other sites More sharing options...

mnkyboy Posted February 1, 2013 Share Posted February 1, 2013 With 3.55s and 33" tires I rarely could use 4th gear. Link to comment Share on other sites More sharing options...

mnkyboy Posted February 1, 2013 Share Posted February 1, 2013 I'm at 4.88 now and it finally feels like I could use 5th. Link to comment Share on other sites More sharing options...
88mj2.5 Posted February 1, 2013 Author Share Posted February 1, 2013 Wow hows the mpgs with that combo? Link to comment Share on other sites More sharing options...
mnkyboy Posted February 1, 2013 Share Posted February 1, 2013 Not sure, I started car pooling just before I did the gears so it doesnt see much time on the road anymore. I would guess 18-20mpg but fuel mileage tends to average a little lower here due to terrain and our ethanol blend gas. Link to comment Share on other sites More sharing options...
