General chaos Posted June 5, 2011 Author Share Posted June 5, 2011 (edited) both transmissions are from 90-94 legacies. i think the fwd is a 92 and my awd is a 93. and what i forgot to really say exactly is can a transmission be made from a 2wd to a awd. is swapping out the tail housing unit all that is needed?

idosubaru Posted June 5, 2011 Share Posted June 5, 2011 (edited) another option is to install the 2wd trans in place of the awd. i did it on my 1996 legacy. didn't even swap the TCU or anything else and it runs perfectly. been driving it for over 50,000 miles now. "POWER" light blinks on start up because it's looking for the rear speed sensor input, but i don't care. i'm sure that would be easily remedied by cutting the rear speed sensor wire, or as a last resort swapping in a FWD TCU, but it doesn't matter. i have a couple other dedicated AWD winter soobs, but good tires are more important than awd for snow driving if that's your main concern. i'd rather have snow tires than awd, but i realize not everyone wants that.

johnceggleston Posted June 5, 2011 Share Posted June 5, 2011 (edited) i think an awd fwd can be made into an awd. most of it is just bolting on the rear extension housing. but you also need to add the clutch drum on the trans side of the transfer clutch. i don't really know what that takes. it has been a while since i looked at one. then you have to make sure the wiring harness on/in the trans has the duty c connector. have you looked for a trans here? www.car-part.com sort your search by distance, shipping is expensive. NOTE: some early FWD trans had a 3.7 ratio, i think. so you'll neeed to avoid those or you will be re-working both ends. the trans would have to be almost free to justify all that work, imho.

General chaos Posted June 5, 2011 Author Share Posted June 5, 2011 ok thanks. i was wondering if some other internals would have to be swapped or not. the fsm's i have looked at. weren't as good as i would have hoped they would be. but they do show quite a bit. we are going to drive it for awhile . and keep looking either for a whole new car or a transmission that isn't outrageous or several hundred miles away.
