will a wrx 05' tranny fit on a 90 Legacy Ls wagon im trying to complete the AWD swap. Somebody is selling it to me for $700 and i want to know if it fits.

Yeah, it will fit, but you'll need some extra WRX parts, like the flywheel, clutch and pressure plate, among others.

well i already took care of it but i dont know the gearing on that tranny cause i bought a 3.9 diff from a wrx 03

To the best of my knowledge, all Impreza non-STI models have the same final drive gearing.

With the 1:1 gear reduction!

The WRX has a 3.90 front diff, a 1.1:1 reduction in the center diff housing, and a 3.545 rear diff. You can't use a WRX tranny with a 3.90 rear diff, or you'll blow the diff.

The STI has a 3.90 rear, but the WRX, and I think the Impreza has a 3.545 rear.

what about the speed sensor. I think the 05' is electric and the 90' s not. what can i do with it?

Just stick your existing cable in the new tranny. It'll work fine.

thanks! now lets get to work

can i use a legacy 94- and later shift linkage and if a can what would i need.

you might try and just use the entire wrx shifter setup and just the body bushing from the legacy.
if i was you, I would make entirely solid shift linkage bushings, and the large round bushing get a poly one from energy suspension. take the bushings apart, go to a plastic shop, and see what round stock they have.
or try and use rod ends through the whole shift linkage, if I was to redo mine i would do that or the hard plastic.

dont get it?

You'd need the whole shifter assembly, including the assembly-shifter "knuckle"
