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.
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.
