I got a great deal on a 2.9 and C3 auto tranny and I was wondering if anyone has done this swap before. What all do I need and what mods. do I need to make to the sammi? I want to run my stock T-case, so will this be possible with the C4? I have heard that all you need to do is put a 2" body lift and your ready to go. Is this really all there is to it? Also, what recomendations are there for fuel pumps? Any info will be great!

i did a 2.3 and a c3 set up in a sj and it is some work. had to cut the crap out of the tunnel. also moved the grill forward a bit and angled the radiator in and used a electric fan in back (engine side). i also used the late model mustang lights and the sj grill. it looks like a cherokee. but alot of cutting is required. also alot longer and transfer case is tricky. i'm using a devorce toy with a 4.5" intermendiate shaft. i say 4.5 because that is the shortest u can make it with 2 u joints. so the drive shaft is really short and a cv is a must. no possible way with out cutting the front end off can u put the tcase in the same place. it will be moved back 5-7" if i remember? or u can cut a the sheet metal and put the radiator in the back but anyways major mods. also yours is longer than 2.3 by at least 4" and u need a bigger radiator than a toyota. that motor is hunk of crap anyways. go with a 4.3 chevy or a 4.0l ford if u want a v6. i would pick the 4.0l. lots of torque. wern't you bedford boys talking about how i should read more books and that my suspension was all wrong? i saw your rigs on your screen saver and i got to tell you i'm not to impressed. you all have stock sammy's. spring over with 33's at the most and maybe a locker. i didn't even see a shackle reversal. i'm not trying to sound like a dick but if u talk the talk walk the walk. where's the cool shit??????????????????????????? if you guys have cooler shit please let me know so i can change the way i think about bedford.

Personally mine is not stock and mabyee you shouldn't judge all of us because of one person.Thats egnough said.

not judging anyone just askink if that was you? every group has one guy that spouts off 4 everone and i was just wondering if u were part of that? sorry 4 any confusion and good luck with the swap. r u stiil going to use it? i can send some pics of mods so u can compare if u want. by the way i also did a toy ifs steering and toy axels with high steer at the same time.

Use a c4 if you can, i know someone on the other bored said that won't work, but I would look into it if I were you.

I was under the impression that any trany that could be used on a 2.8 could also be used on a 2.9, and maybe 4.0.


The c4 can be shortend 5" which makes using the stock tcase easier. finding the parts to shorten it is the hard part.

I have a 2.8/c4 and it works good for me. it was an easy swap.
the two main things that i had to do were to widen the base of the trany tunnell, and move the tcase back 2".

I am not sure what he has planned to do yet.The only reason he asked about this swap is he can get the motor and tranny for 250$.As for the work it would probably be myself doing it for him.I'm getting ready to do goofie leaf's for him in a few weeks.
suzuki w/the HEAT,I would like pics of your high steer if possible.Also sorry for that but I got to protect my bros.I know it wasn't me, I feel anyone is entitled to whatever they want and I feel noone should judge another for that.:usa:
