Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Drain the Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set and carefully lower the pan to drain fluid.

3. Remove the Transmission Pump

Disconnect any electrical connectors and hoses attached to the transmission pump.
Remove the pump mounting bolts.
Gently pull the transmission pump out, taking care not to damage any surrounding components.

4. Inspect and Clean

Inspect the removed pump for wear or damage, focusing on the gears and housing.
Clean the pump mounting surface on the transmission case with a soft cloth and appropriate cleaner.

5. Install New Transmission Pump

Position the new transmission pump in place and tighten the mounting bolts to the manufacturer's specified torque.
Reconnect all electrical connectors and hoses.

6. Refill Transmission Fluid

Replace the transmission pan with a new gasket if necessary, and secure it with bolts.
Refill the transmission with the recommended type and amount of fluid as specified in the owner’s manual.

7. Final Checks

Reconnect the battery.
Start the engine and allow it to idle while checking for leaks around the pump and pan.
Cycle through the transmission gears to ensure proper operation.
