April 27, 201015 yr So I just replaced the AWD auto trans in my 90 Legacy with a used unit, and I am noticing it has the same soft, slightly hesitant 2-3 upshift and 4-3 downshift the old transmission had, exactly how it behaved when I first got it with the original trans, 3 years later and 3rd gear goes out completely (the reason I had to get a different trans). It's just such an unsure shift compared to the snappy 1-2 and 3-4 shift. Not really wanting to burn up another transmission, I'm wondering if this is how they all shift, or would it be some common problem affecting both transmissions? Do the TCM's in these cars go out frequently, where it would cause the shifts into 3rd to be so soft? And if I do try a module, should I get one to match the year of the trans, or the year of the car (tranny is from a 94 wagon, mine is a 90 wagon)?

First off, you need to swap you're rear diff. You're 90 is a 4.11 ratio, and the 94 trans will be a 3.9 Surprising that you haven't had toubles yet. Maybe you're transfer clutches are worn allowing for enough slip. Not good for them though And yes, I would try a different TCU.

Hah yeah that was a different thread LOL http://www.ultimatesubaru.org/forum/showthread.php?t=111302 And thanks for the input, I haven't been able to find anything definitive on here about trans computer compatibility.
