85ish Bronco T18

[FrankinCJ7]

Question for the guru's out there.

I am putting together a 84 CJ7 with a AMC 360, SR4 tranny (there, I said it!), Dana 300 tc. I just picked up a locker and the Warn full floater kit for the rear end.

Obviously, the SR4 is the weak link. I found a salvage yard that has a 85 or so Bronco with a T-18 in for $250.00.

The question, what will it take to get it into the drivetrain?

Thanks in advance!

"Thanks in advance!" .... Exactly, hit the Advanced Adaptors and NOVAK websites they will tell you everything you will need to know.

Check and be certain that the Ford Bronco Transmission is a T-18 . It may be a NP435. Either is a good Transmission , the NP435 has a lower 1st gear, and can be adapted into a CJ. Most of the swap information I've read indicates that the preferred T-18 is from a 2wd vehicle. The NP435 either 2wd or 4wd works (from my research).

Mine was from a 2wd (I am running a Ford 5.0L, so I'm using a stock Ford bellhousing):





Either Transmission will need to be dis-assembled. MAW do a complete rebuilt because you will need to replace the mainshaft with the conversion shaft.

Not certain about re-using the SR4 Bellhousing, I believe a T-176 bellhousing will bolt to the Ford 'butterfly' pattern T-18 (or NP435). A new or conversion pilot bearing should also be on the list.

Skid plate modifications will be necessary. Perhaps even a 'drop'. Stock CJ's with T-18 's had 7/8" of spacers installed between the skid/cross-member and the frame. I used a skid/cross-member from TDK with no drop and no holes for the transmount or torque arm drilled. I aligned the drive train, then drilled the holes for them:













Some sheet metal needs to be trimmed from the floor pan:



Possible gear shift modification:



New Transmission cover:



New or modified driveshafts may be necessary. On my CJ5 , I had a Tom Woods CV style rear installed, and a regular Tom Woods front.

Wow, that's awesome work!! I appreciate the info, a little more involved than I want to get at this point.

Anybody have a T-176 in or near AZ?
