1998 Subaru Legacy Repair Question
1998 Subaru Legacy P0740 code
1998 Subaru Legacy 4 cyl All Wheel Drive Automatic 154000 miles
Not sure if trans or electrical problem. Car has rebuilt trans w/20,000 miles. Use for paper route so rough driving. Got P0740 code twice in 3 days. Son has repalced TCC solenoid on another car, but not Subaru. Does the valve body have to be removed to replace TCC solenoid? He's worried about bearings inside. Any special handling required? Should we check something else before replacing the solenoid? He would like a diagram but all I can find is full manuals. Basically anything you can tell me would be great. Thanks so much.
