Common problems & symptoms
Problems and symptoms reported for this transmission, compiled from repair sources. Not a complete list.
!
Intermittent no forward/reverse
Vehicle may intermittently lose forward or reverse engagement with a flashing PRNDL or 'Range Shift Inhibited' message, often linked to erratic input/turbine/output speed sensor readings.
!
F-trim valve sleeve wear
Wear of the F-trim valve end sleeve causes torque converter clutch surge and slip, setting code P0741; prolonged slip can overheat the fluid and damage the torque converter.
?
Intermittent limp mode, loose connector
Transmission intermittently enters limp mode, failing to upshift/downshift and clunking into gear; traced to a loose wiring connector at the rear of the transmission housing.
!
Sticking E-shift valve
The E-shift valve (called shift valve 3 on 6-speed units) can stick in its bore so the pressure switch fails to change state, setting code P0872 and forcing the transmission into failsafe/3rd gear starts.
!
Warped valve body castings
The two valve body halves can warp and cause internal cross-leaks between hydraulic passages, requiring flat sanding during rebuild since most years use no separator plate gasket.
