A340H to A340F 91 4runner
« on: Jan 30, 2015, 10:21:20 AM »
I've been doing a lot of searching but haven't found any real answers that apply to me.

I have a 91 4runner 3.0 V6. A340H.  I want to consider an A340F swap simply to improve on road performance and economy. I want to run the stock transmission and transfer case and simply just have them separated as the F set up comes. I won't ever care about lower tcase gears or dual units and this is just a daily driver and see occasional light duty off road use.

Is this a simple swap where the parts all simply swap over or will there be additional adaptors or customizations need and what year A340F should I look for?  Does the F still share the same failure prone solenoids that the H sees being the same basic Trans ? 

I've searched and there is a lot of information out there but mostly on swapping the run dual t cases and what not and doing this swap with engine swaps that I don't need to consider.

A 3.4 trans would bolt up since it is of the same engine family. I think all of the 3.4 have driver drop transfer cases. You'll have to sort this out what to do.

I don't want to deal with that much craziness. What about the AW4 jeep swap or is there a way to just run a divorced case with the stock transmission.

lets open this thread back up, what did you end doing with the 340F swap? I believe I got a 340F from a 95 t100 with the 3.0 (I think that only because the t-case is pass drop).
Anyone know if the speed sensor for the TCU will work for my once 340H set up?

yes, I read through that and have it printed out as well. the only thing I'm stuck on is whether or not I have to modify my tail shaft housing for the speed sensor.  :headscratch:

if the A340F I  have came out of a 95 t100, I don't need to modify the housing right?
