I need a auto trans for my 94 legacy turbo wagon, will a non-turbo trans bolt up to it? Are the houseings different or just the internals?

First off, are we talking about the auto or the fairly rare 5spd?

Next, as far as the manual goes no. The turbo 5spd used a different drive ratio than the non-turbo.

well....if you keep the front diff portion.....you could bolt it up....final drive ratios are different between n/a & turbo legacies.....depending on year. Also, the turbo legacy auto is a little more beefier. More clutch plates and such.

may want to ask one www.bbs.legacycentral.org too.

here's the final drive ratios of other subaru models...

---------------------------------------------------------------------------------
Legacy Turbo Models:

Automatic transmission gear ratios:
final drive ratio - 4.11

Manual transmission gear ratios:
final drive ratio - 3.90

Impreza 2.2l L models:

Automatic transmission gear ratios:
final drive ratio - 4.11

Manual transmission gear ratios:
final drive ratio - 3.90


Impreza 2.5RS models:

Automatic transmission gear ratios:
final drive ratio - 4.44

Manual transmission gear ratios:
final drive ratio - 4.11


WRX 2.0l models:

Automatic transmission gear ratios:
final drive ratio - 4.11

Manual transmission gear ratios:
final drive ratio - 3.90


Impreza WRX STi models:

Manual transmission gear ratios:
final drive ratio - 3.90
--------------------------------------------------------------------------

The transmissions from the above cars will work on your car, however; if you decide to go to a tranny with a different final drive ratio than your original one you WILL have to either get a matching rear diff or swap in your front diff into the other tranny. Best bet is to change your rear diff as well... The legacy turbo tranny is one of the strongest ones out there so be weary of the strength of non-turbo tranny models. Also take into account that if you go to a shorter final drive ratio tranny you're rpm's will be higher when cruising on the highway, you may not want that (fuel mileage, noise, etc...)

hope this helps

Nuwan, where did you get your info from? I thought the turbo legacy 5spd had a 4.11 in it.

I had a 5 speed turbo trans (from a 93).... Junked it. :D

As for the question about the dude's car...turbo wagons are all automatic in that vintage. the only turbo legacy with a 5 speed is a sedan.

I have three different salvage yards looking for me but the information they have says that only 92-94 will fit my 94 wagon.

I have located an auto trans from a 1991 turbo Legacy on my own, is it the same as my 1994? Why do the salvage yards think they are different?

I don't think they are.... I would be almost willing to bet the bank on the transmissions being the same 90-94 turbo wise.

I would take a crap shoot at it....If you can't find one used I can hook you up with a guy that gets Jap import ones and you can have him install it. He is local to me (Lancaster County PA). Let me know if Ican help.
