4T65E Solenoid Kit, new and ready to install. Fits the 4T65E. Ships fast from the USA.
This is our lowest-cost complete solenoid kit for the later GM 4T65E, the four-speed automatic behind the 3.4, 3.5, 3.8, 3.9 and 5.3 engines in 2003-2011 front-drive and all-wheel-drive GM cars and vans. If a Chevrolet Impala, Monte Carlo or Uplander, a Buick LaCrosse, Lucerne, Rendezvous or Terraza, or a Pontiac Grand Prix or Aztek is stuck in one gear, flaring between shifts, or throwing converter clutch codes, the solenoids on the valve body are a fair-priced first repair once the wiring checks out. The photo shows what ships: two shift solenoids, two spool-type solenoids (pressure control and converter clutch PWM), and the later pressure switch manifold. It is a new aftermarket kit, and every switch is bench-tested before it ships.
In the 4T65E the engine computer runs the hydraulics through these parts. The pair of on/off shift solenoids are switched in combination to stage first through fourth gear. The pressure control solenoid is pulsed to set line pressure, so it decides how hard each clutch pack is squeezed. The PWM solenoid ramps the torque converter clutch on gradually at cruise. The pressure switch manifold reports the selected range back to the computer so it can pick the right shift and pressure tables. All of them are fed from the actuator feed limit valve in the channel plate, so they share one oil supply and tend to wear out together.
Start with the wiring. Transmission Digest documented 2006-2007 4T65E cars setting P0742, P2761 and P2764 because a retaining clip chafed through the internal wire harness, and swapping solenoids does nothing for that fault. Check each circuit at the case connector, then at the solenoid. If the electrical checks pass and shift adapts are still at the limit, compare commanded and actual line pressure; Sonnax lists a worn AFL valve bore as a cause of the same P1811 and P0741 codes. Our 4T65E shift solenoid guide covers the code-by-code checks, and 4T65E common problems explains when the real failure is a clutch pack.
The application list for this kit runs from 2003 to 2011: Buick Allure 2005-2008, Century 2003-2005, LaCrosse 2005-2009, LeSabre 2003-2004, Lucerne 2006-2011, Park Avenue 2003-2005, Regal 2003-2004, Rendezvous 2003-2007 and Terraza 2005-2007; Chevrolet Impala 2003-2011, Monte Carlo 2003-2007, Malibu 2006-2007 with the 3.9, Uplander 2005-2008 and Venture 2003-2005; Oldsmobile Silhouette 2003-2004; and Pontiac Aztek 2003-2006 and Bonneville, among others. It does not fit the 1997-2002 4T65E, which used a different valve body and pressure switch; those cars need the 1997-2002 solenoid kit. Interchange numbers listed for the kit include 24219819, 24225825, 24216426, 24227792 and 10478124. Match the pressure switch and solenoids on your valve body to the photo, or send us your year and VIN. See every part for this unit on the 4T65E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2003-2011 GM vehicles with the 4T65E, from the 2003 Impala and Century to the 2011 Lucerne and Impala. The 1997-2002 4T65E uses a different valve body and pressure switch and needs the earlier kit.
Two shift solenoids, the pressure control solenoid, the converter clutch PWM solenoid, and the pressure switch manifold, as shown in the photo.
Only if the solenoid is at fault. On 2006-2007 cars a chafed internal harness commonly sets these codes, so test the circuit at the case connector and at the solenoid first.
No. It is a new aftermarket direct-replacement kit, which is why it costs less than our other complete 4T65E solenoid sets.
Yes. Clear codes and reset the transmission adapts with a scan tool, then drive through every gear so the computer can relearn shift times with the new solenoids.
DEXRON-VI. Check the level with the engine running and the fluid at operating temperature.
