In the 2002 Pontiac Grand Prix, the shift solenoids are located inside the transmission valve body. The shift solenoids control the flow of transmission fluid to engage different gears and facilitate smooth shifting. Specifically, code P0753 refers to a malfunction in Shift Solenoid A Electrical.

To access the shift solenoids, the transmission pan and valve body need to be removed. Here are the general steps involved:

Raise and secure the vehicle: Use jack stands or a vehicle lift to elevate and secure the Grand Prix, ensuring a safe working space.

Drain the transmission fluid: Locate the transmission pan and place a drain pan beneath it. Remove the pan bolts, allowing the fluid to drain completely.

Remove the transmission pan: Once the fluid is drained, remove the remaining bolts securing the transmission pan and carefully remove the pan. This may require gently prying it loose.

Locate the valve body: With the pan removed, you'll have access to the transmission valve body, which is located directly above the pan. The valve body houses the shift solenoids.

Identify the shift solenoids: The shift solenoids are small cylindrical components attached to the valve body. There may be multiple shift solenoids, labeled A, B, C, and so on. Shift Solenoid A is typically one of the first solenoids from the front of the transmission.

Replace the faulty shift solenoid: If you've identified Shift Solenoid A as the cause of the P0753 code, remove and replace it with a new solenoid. Ensure you're using the correct replacement part recommended for your vehicle.

Reassemble the transmission: Reinstall the valve body and secure it with the appropriate bolts. Then, reinstall the transmission pan using a new gasket. Torque the pan bolts to the manufacturer's specifications.

Refill transmission fluid: Refill the transmission with the appropriate amount and type of transmission fluid, following the manufacturer's guidelines.

It's worth noting that working on the transmission and its components can be complex and requires a certain level of mechanical knowledge. If you're unsure or uncomfortable with this process, it's recommended to consult a professional mechanic or a transmission specialist who can diagnose and repair the issue for you.

Can you upload an image of what you are seeing so I can help? The code is for the electrical connection so the solenoid might be shorted which is common.

Sorry the pan you need to remove is on the side of the transmission to replace the shift solenoids. Here are the location and instructions in the images below. Check out the images (below). Please let us know what happens.

So, do I have to drop the transmission to get to the shift solenoid?

It looks like it. You may be able to remove the transmission and maybe an engine mount to lower it enough to remove the side pan. Here is how the job is done. Check out the images (below). Please let us know what happens.

I just found out that the paperwork on the Grand Prix is wrong. It is a 1999 Pontiac Grand Prix. Any chance you could tell me where the shift solenoid is located still?
