1996 Lexus SC 300 6 cyl Two Wheel Drive Automatic 210000 miles
Removed valve body for a complete fluid drain. Top & bottom valve body gaskets shot. Opened up valve body to replace gaskets. Used a 1990 Supra A340E diagram for procedures, rubber balls, colored springs, etc. Reinstalled valve body. Works fine when cold, however, major slip in reverse & no upshift from 1st to 2nd, etc. When at operating temp. Disconnected solenoid harness to test manual operation - same problem. Removed valve body & ran compressed air thru ports to check operation of reverse, 1st, 2nd, 3rd, O/D, etc. - All sounded as they should. What to do, what to do? Valve body problem? Why fine when cold but not when warm?
have the same problem?
