Have a 97 legacy with a 3.90 final drive, need a new tranny. Have the option of getting a 97 Impreza transmission. The question here is, both have 3.90 final drive. All the gears are a bit shorter ,The one Impreza has a 3.333 fifth gear, while mine has a 3.416. The difference being the 1.8l Impreza vs. the 2.2l Impreza had different transmissions. The 1.8l has all the same ratios as my legacy, the 2.2l has shorter gears. What if any difference would it make putting that transmission in my legacy.

My transmission is TY752VACAA the donor trans is TY752VA5AA. Both have exactly the same gear ratios ,except for 5th. Mine is .780 the donor is .825. what if any issues might I have, without swapping the rear diff or driveshaft. The Impreza that Im getting the trans from was originally an automatic. Someone had done a manual swap on it, I checked the vin decoder. The donor has a 1.8l ej18 engine in it now. I have a 2.2l ej22. I’m unsure of the rear diff on that (donor vehicle )if it was swapped when the manual was put in. But with all the gearing the same other than 5th, should I be good with just swapping the transmission?

Awesome to find this thread, I'm doing a 2001 outback front seats into my 97 legacy wagon, I believe this will help tremendously.
