4T65E Governor Pressure Solenoid, new and ready to install. Fits the 4T65E. Ships fast from the USA.
Despite the governor pressure solenoid name on this listing, the part shown is a pair of new ACDelco shift solenoids for the GM 4T65E. If your Impala, Grand Prix, LeSabre, Century, Monte Carlo or minivan is setting P0753 or P0758, starts out in a high gear, or will not upshift, these are the two solenoids that decide which gear the transaxle is in. The 4T65E does not use a governor at all, so if you were searching for one, this pair or the EPC solenoid is almost always what you actually need.
The PCM selects gears by switching Shift Solenoid A (the 1-2 solenoid) and Shift Solenoid B (the 2-3 solenoid) on and off in set combinations. Each is a simple on/off valve that opens or blocks a signal circuit in the channel plate, and the shift valves move in response. Both solenoids share the same body style, which is why they are sold as a pair; this listing names them the 1-2 and 3-4 solenoids. Their feed oil comes through the AFL valve, which Sonnax says limits it to 115 psi, so a solenoid can only do its job if that circuit is healthy. When both are de-energized the valve body falls back to a fixed gear so the car can still be driven.
P0753 and P0758 are electrical codes: the PCM commanded the solenoid and could not verify the circuit. Check resistance at the case connector first, then at the solenoid itself with the side cover off. If the solenoid reads good and the circuit does not, the problem is wiring, not the part. A late or soft shift with no electrical code is usually pressure-related, not a shift solenoid, and P1811 in particular points to the EPC solenoid, the AFL bore or clutch clearance. Our 4T65E shift solenoid symptoms guide breaks down which code goes with which part, and input and output speed sensor symptoms covers the sensor faults that can look like shift trouble.
The listing fits the GM 4T65E and does not narrow it to a year range. The on/off shift solenoids were not the part GM split by year; the EPC solenoid was. Still, pull one of your old solenoids and compare the body, mounting tab and connector before installing, or send us the year and VIN. If you want every solenoid in a 1997-2002 unit replaced at once, see the 1997-2002 4T65E four-piece solenoid set. All other parts are on the 4T65E parts page.
If you have the pan down too, add the 4T60E/4T65E filter and pan gasket kit. On a 2003-up unit with firm shifts or P0748, the 4T65E pressure control solenoid 2003-2011 is the other common replacement.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Two new ACDelco 4T65E shift solenoids, the pair that controls the 1-2 and upper shifts. No EPC or TCC solenoid is included.
No. The 4T65E uses electronic shift solenoids and an EPC pressure control solenoid instead of a governor. This listing is the shift solenoid pair.
P0753 or P0758, the shift solenoid A and B electrical codes, after the wiring and connector check good. P1811 is a long-shift code and usually points elsewhere.
Many owners do, since both solenoids have the same age and miles and the cover is already off. Replacing only the faulty one also works if budget is tight.
The listing says it fits the 4T65E without a year limit. Compare your old solenoid body and connector to the photo, or send us your year and VIN before ordering.
