Hello all. I'm new to Toyota trucks and i just picked up an 82 4x4. Well it has a bad trans. So now for my question. A friend of mine is going to give me a g52(I think that's what its called) out of an 84 22r truck and I haven't really be able to find much about swapping this trans in. Other then it's 4.5 inches longer. I have access to the whole truck for parts. So anything I'd need is available off the truck. They are both short boxes. And I've read that I'll have to take the drivelines and yokes too. Any info would be helpful. Thanks.

 

gonna need to adapt your crossmember, it is gonna be moved back so you will need to fab new mounts or use some ubolts

 

I've heard of people being able to used the driveshafts from the donor vehicle and not having to do modifications. But it seems like convential wisdom says you're going to be shortening the rear driveshaft, and extending the front. The 79-83 shortbeds were a little shorter than the 84-88 short beds. But maybe not so much shorter that you couldn't still make the 84 driveshafts work, since there's some room for compression & extension in the driveshaft obviously.

This is only from stuff I've read...it seems harder than it should be to get people who have actually done these swaps to come out of the woodwork and share their knowledge.

So some of what I've heard is for W-series trannys, not the G-series like you got. But I've heard of people having to:

Cut the cab floorboards a bit, since the gear shifter is located a little farther back on the longer tranny.

Lengthen the front driveshaft and shorten the rear.

Move the crossmember back slightly.

Pound out the underneath of the cab a little, due to the transmission either sitting higher or being larger all around...can't remember which.

None of these are really very major hurdles, especially if you have some fabrication skills or know someone who does. And you'll probably only need to do certain ones, and not others.
