LIGHT TRUCK: 1994 E-150, F-150
ISSUE:
Vehicles may experience a higher-than-expected engine RPM during the 1-2 upshift or a 1-3 upshift (no shift into 2nd) concern. This may be caused by a damaged intermediate clutch outer piston seal, due to an improperly machined groove for the outer piston seal.
ACTION:
If the transmission requires service, and the outer piston seal is worn or damaged, the intermediate clutch piston (F2AZ-7E005-A) should also be replaced to avoid a repeat repair. Refer to the appropriate Service Manual, Section 07-01, for piston removal and installation instructions.
