shifting notchy, doesn't seem as smooth after tranny oil change
Hi everyone. A couple of weeks ago I replaced the transmission and the rear diff with Valvoline 75W-90 gear oil. It doesn't seem to shift as well anymore, and it is especially rough when its cold. When I filled it up I was actually over the FULL line a little bit, but though once it all settled and ran it it would drop a little bit. It hasn't dropped. Do you think that this could be a problem. It is just a little bit over the full. I figured it wouldn't be bad to go over a little. It happens...right? Anyway I'm trying to figure out if I'm just tripping about it shifting bad, or if I put the wrong stuff, or its too full. Can anyone shed some light on things?

Locate some Swepco fluid, flush your tranny and put in the Swepco.
If you can't locate it in your area, contact Noah of LICMotorsports, he mentioned to me he has shipped it, but that might only be to previous customers.

I've been driving it with the Valvoline for 3 weeks. You think that is fine? I don't wanna do severe damage to the tranny.

That was all I can find in Amado, AZ where I did the tune-up. Now that I'm back maybe I'll try to flush it completely. Anyone have any other suggestions on gear oil to use?

Had problems with valvoline oil, replaced it with Extra-S. Get some Subaru Extra-S oil and be done. Best gear fluid for these transmissions period. I'v got 145k miles on my original transmission.

I've been needing to change the transmission fluid and hated the idea of spending so much money for extra-s.
I've asked the "what transmission fluid" question to a bunch of people. Almost all of them say OEM extra-s.

I bought the car used with about 84k miles on it. clutch has been replaced before but not sure when.
I was told that this could also be a bushing? anyone know about this and possibly have a DIY bushing replacement guide?
And while we're on the topic, anyone have service manuals on a PDF?
