Hey guys. I was reading the thread concerning 'C' solenoid issues, with the torque bind problems, etc. This was one of the problems I had when I bought my '96 OB, and with help from several people here, I replaced the solenoid and solved it. But that car was a automatic... my new rat is a 97 5 speed Impreza OB. The AWD works flawlessly, with no torque bind but plenty of power to all 4 wheels. I guess this falls under my old mantra 'if it aint broke, dont worry about it' but now Im curious. How is the torque split handled on standard trans Subies of that vintage? Is it all mechanical? Obviously, I have no trans temp light. Hey, if one of you guys are bored, I'd love to hear your input. (I did search around a little but didnt find what I was looking for)

I believe its a viscous coupling in the transmission. Strickly mechanical, it either works or it not. Nothing you can do but replace it if it fails.

Its a sealed viscous coupling, just like the a LSD. It will give no warnings that it is in pain if there is a problem. Just like all AWD cars make sure the tries all match and are properly inflated, and it will last for a good long time.
