Hi folks, I am a new member to UltimateSubaru. My wife has a 2003 Forester 2.5ix and I have a 99 OBW. I have done some internet searching a for a problem with my OB. When I accelerate rapidly straight, or moderately on a turn both from a stop, I get a pronounced shudder (which feels like it is coming from the rearend). I inserted the FWD fuse, and the shudder went away. (And on hard turning acceleration I could smoke the front tires, HE HE!). From what I've read on various posts, It may be the "DUTY C SOLENOID"?? BTW, it is a 2.5, with Auto trans. I appreciate any troubleshooting info or help. Thanks. I am a fair, but slow mechanic and electrician. Thanks again.
