What automatic transmission do I put in my '76 FJ40? (1 Viewer)

[rivercochran]

Hey there,

I have '76 fj40 with the original 4-spd transmission and 2F engine. Due to a bulging disc in my lower back, I think I'm going to have to switch out the 4-spd transmission and put in an automatic transmission. FYI, I use my cruiser as a daily driver, no rock crawling. Most of the car is original although it does have an upgraded carb, headers and ignition. The engine has 140k on it and was professionally rebuilt about 13k ago.

Question 1 - Which automatic transmission should I have put in?

Question 2 - What other equipment will I need to hook up the transmission? For example, an adapter of some sort.

Question 3 - Any ideas on good places to purchase these parts?

Best regards,

josh

i can't believe i'am about to say this........if you're going to put an auto in it.........you might as well finish the job with a v8 in front of the auto.

can't say i recall reading about alot auto's behind F's, auto's behind 350's on the other hand...

i thought an Auto behind a 3f is bad enough in the FJ80...an auto behind an F in a 40...i wouldn't

I would do a 4L60e.... I agree with the V8 swap as a good additional upgrade. Advanced Adapters has all the adapters. The adapters are around 1000 total.

i put a 350 with a th350 behind it, using advance adapters adapter between the transmission and t/case. i placed the engine as far forward as possible, in order to get a long rear driveshaft. but i put it so far forward that i can't fit an electric fan in front. so keep those kind of things in mind. i also used a hurst shifter, which was really easy to install. if you have any specific questions, pm me, cuz i may not check this thread again.

I'd toss a 3FE complete drivetrain from an FJ62 into the rig.
Since a 40 is lighter than a 62, this might work nicely

Will the A440F work behind an F or 2F?

If you are going to all the work it'd probably just be better to put in the whole 3FE combo. At least around here that's the only engine swap you can legally do.

yeah
It will bolt right up.

really?!?! wow i seriously actually didn't know that. Now I want the 3f myself. Can you use the 3FE with the 74 4spd? (end hijack)

 

[Advent]

Yes, you can swap a 4 speed onto the 3FE.

The current fad is to take the 3FE head and swap it onto a later 2F block.
