Hi all,
I've lurked here for years but first time posting. Experiencing torque bind in my 96 Impreza (2.2 4EAT). 240k miles but transmission was replaced with used unit not long before I bought the car - PO says it's got around 100k.
When I bought the car it had no torque bind at all - drove it home and put it up on stands to replace a wheel bearing and struts. Between sourcing parts and work it wound up in the air approx 1 month. When we finally got it back together parking brake was frozen - was eventually able to free it by applying throttle. Not sure if that could have caused any damage but suppose it's possible as immediately upon first test drive torque bind was evident.
Symptoms - inside rear wheel "chugs" during tight turns, which is classic torque bind from what I've read. Two weird aspects to it - sometimes rear end will give a slight wiggle starting from a standing stop in a straight line, and under heavy throttle it basically disappears. For example, if I punch it around a right hand turn the car will just go. Do the same thing slowly and can definitely feel some bind. This may also be common but not that I've seen.
What I've already checked - no TCU errors; AT Temp light illuminates approx 2 seconds during startup, then off - no flashing. If the FWD fuse is installed all torque bind issues disappear so I think my Duty C is fine.
Bind occurs on both the original crappy tires it came with and my new set of rallx tires so I'm pretty sure it's not a wheel diameter issue.
So that would lead me to think that a fluid flush is needed, but the fluid seems brand new so not sure that helps me any. Maybe add some LSD additive? Not really sure what my next steps should be - any other ideas?
