how do you tell what transmission I have, I got one from a yard a while back and Im not sure if its 2wd or 4wd, and second does it matter if its 2 or 4wd, can you put a 4wd trans in a 2wd car? I only ask because I am in the process of buying a 94 2wd with a bad trans, and I have a trans in the garage, thanks Johnny

first get the number of the top of the trans I can tell you what it is.like this TZ1022M1AA. second 4 wheel drive has a output shaft out the end. next lot of work to convert to 4 wheels drive. also the 2 wheel drive are 3.70 gears.

They're are not very many 2WD Subaru transmissions around. For many years almost all Subarus have been 4WD.

so the one I have in the garage on a stand is TZ102ZM2AA- KR, I see the output shaft on this one , so I would tend to believe it is 4 wheel drive, do you think its possible the one Im trying to buy 1994, is 4 wheel drive but the owner doesnt know its 4 wheel drive, as I know on my 92 there is a fuse to pull to make it 2 wheel drive. if by chance the 94 is 2 wheel drive , would my 4 wheel drive trans work in it?

You're doing a lot of wishful thinking.
Your transmission will have 3 outputs if it is 4wd. Left and right for the front wheels and rear for the back wheels.
The '94 is likely a 2wd if he says so. It takes 10 seconds to look under it and see if there are CV axles going to the front wheels and a driveshaft to the rear differential. 2wd is front wheels only.

A 4wd transmission can only be used on a 4wd car and a 2wd transmission can only be used on a 2wd car.

Personally I wouldn't buy a 2wd SVX for any price, especially with a blown transmission.

If I could get him to send me the VIN, could I go to the subaru dealer and have them run a check on the car to see what it was born with?

You could run it online even. Just

Subaru VIN check.

Svxnavyvet.... where are you getting your info for the trans serial numbers? I just picked up a sti transmission for my 92 svx and am getting conflicting info from the salvage yard vs. Internet search...

Any chance you can decipher BE-TY856UW6AB ? I ran it by the NASIOC forum and no response.

Was also curious what 258233 (to the left of the transmission code) meant.

Any help would be much appreciated.

so if I have a 4 wheel drive trans and this car is 2 wheel drive, if I pull a rear sub frame, axels, basically everything from a 4 wheel drive svx and change it with the 2 wheel car everything should be good .......right?

SVXMAN2001 · #14 02-22-2022, 06:16 PM

I have heard of some contemplating doing it over the years, but it is a lot of work...all for what? The 4EAT is flawed as we all know, you'd also be well advised to have an an aftermarket trans cooler if sticking with the 4EAT.

Aside from what you mentioned, you'd also want the rear hubs as well.

Does the FWD and AWD TCU differ in any way?

Blacky · #15 02-22-2022, 06:51 PM

You must be younger and far more patient than I am.
Converting a 2wd to 4wd is a big, expensive task.

The TCU is different also.

Do a search of this forum and you'll find a lot of information on doing a swap.

Why not just buy a 4wd SVX that is functioning and you will have a spare transmission.

Are you even sure the transmission is in good working order?
