Finally got me a CJ5, few questions

Snagged a 1968 CJ5, its lifted on 33" buckshots, has a Buick V6, the 3 speed and original transfer case/axles, I beieve he told me it has 3.88 gears and an auburn locker in the rear. It ran and drove so I bought it for 1000. Locally you can get Th350's rebuilt for around 200 bucks. How hard is it to put one in there? Figured it would be a nice combination with the Buick V6. Any insight is appreciated. Oh and I'll post pics as soon as I can. Also the stock D18 transfer case (I believe thats what in these) is starting to whine heavily, how hard is it to rebuild them?

Re: Finally got me a CJ5, few questions

One thing you can do to rebuild the transfer case. Look into upgrading your coutershaft to 1-1/4". You should have a 1-1/8" now but could have the 3/4" version. Also, don't use cheap countershafts as they will wear quickly. You probably won't have room for a th350 transmission but if you move the engine forward, you might. The adapter for the transfer case will be expensive but you can offset the cost a bit by finding a buick bellhousing pattern transmission. Stock gears might be 4.88 and that auburn will be a limited slip not a locker.

A CJ5 is a bit short for a TH350, but it has been done. My buddy with a '79 Yota 4x4 has a 231 Buick V-6 with a TH350 behind it. He rebuilt it and dropped in an RV cam and Edelbrock intake and carb. Had to play with different torque converters till he found one that worked right with the combo. It motivates his 'yota nicely. Your Buick V-6 should be an odd-fire 225.

Re: Finally got me a CJ5, few questions

Thank yall very much for all the insight. I was just pondering on the automatic idea, but the 3 speed is growing on me. Possibly a newer 4 speed would be a fellow swap for me? Today I went to get the water pump, little did I know (didnt catch pilots reply in time) that from 1966-1972 they put 225 (3.7) buicks in there. Pretty neat, but the rescent owner told me he swapped in a 3.8 buick, so I ended up installing a water pump that had an inch to much of water neck, also infatuated with the fact that they put oil in the air cleaners like much older VW's. I love the stock motor, but for peeps sake of thinking in the future, if this engine blows up shouldnt its newer anscestor the 3.8/231 buick bolt right in there? I happen to have a buick Grand National motor sitting in the geerage so if so the Cj would be its new home if this motor lets go.

I also had to zip-tie the clutch fork to hold it out, it slides back in and you lose nearly all of the clutch, I figure when they tore the tranny out to rebuild it they probably didnt install something right.

Thanks for the transfer case input, I forgot the D18's were the passenger side offset transfer cases. Is there by chance a certain transfer case rebuild kit out on the market or do you have to piece everything together.
