4T65E Transmission Solenoid Kit 6-Piece with Harness

Six-piece solenoid set with the internal wiring harness for the GM 4T65E four-speed transaxle, covering roughly 2003-2011 Chevrolet Malibu, Impala and Monte Carlo, Pontiac Grand Prix, Buick LaCrosse and Lucerne, Oldsmobile Intrigue and the Volvo applications that used the same transaxle. The set replaces the shift solenoids, the TCC/PWM solenoids and the pressure control solenoid in one shot instead of chasing them one at a time.

The 4T65E hides its solenoids on the valve body under the side cover, and by the time one fails the rest have the same miles and the same varnish on them. Typical symptoms are a hard 1-2 or 2-3 shift, no 4th, a converter that will not lock or drops out at cruise, or shift solenoid codes P0751, P0753, P0758 and pressure control codes P1811 and P0748. Replacing the whole group with a fresh harness also fixes the chafed and corroded internal connectors that set intermittent electrical codes with no mechanical failure behind them.

Cross-references on the kit include G4T65E, 24237264, 10478124, 24219819, 24212690, 24227792, 8683187, 10478146, 24203699, 24203267, 24209121, 24212327, 24214974, 24227747, plus the common aftermarket numbers TCS32, TCS44, TCS77, TCS342, TKS10, TKS23, SL10020 and 2N1204. Drop the pan, pull the side cover, swap the solenoids and harness, then clear codes and relearn the adapts. Check your own part numbers against the list before ordering - the 4T65E changed connectors across its production run.
