Topic: Question for Marlin! A340F swap 91 4Runner!

[Sweetkittens]

I have a 91 4Runner 3.0L V6, I am in the process of rebuilding the engine and doing a solid front axle swap. Along with that I want to put an A340F in it. I just pulled the A340H out and took the solenoid wiring, throttle cable, bell housing and oil pan off. I was wondering what else I will need to do before the A340F will just bolt right in, as far as I understand I will not need it machined, correct? Also can I use an A340F off of any year/model truck?

I would appreciate any advice!

If you can find one of the very very very few A340F's out there, which I did and I used the Marlin V6 adapter, to bolt to the A340F and dual cases behind that with a Marlin dual case adapter of course. I have seen or heard of only a handful of A340F's in existence in a pre-Tacoma Toyota. The other issue is getting the right torque converter/flex plate combination. The input shafts of the A340's have different spline counts and flex plates have different bolt patterns for the torque converters. But other than all that it bolts right up. Oh yeah, I love wheelin mine with the RZ I swapped in.

Thanks for the reply. Correct me if i am wrong but it is my understanding that any Toyota truck with a 4 cylinder engine that is an automatic 4-wheel drive, has an A340F in it, correct?

No. The difference is simple to tell, 1 trans oil pan or 2, 2 is bad. I know of guys who have searched and search and never found one. There was a thread about this several years ago, I don't think anyone could nail down the model that the A340F came in.
