Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Identify the Leak Source

Inspect the transmission pan for cracks or loose bolts. Tighten bolts to manufacturer specifications if they are loose.
If the leak is from a seal, such as the input, output, or axle seals, proceed to replace the affected seals.

3. Remove and Replace Transmission Fluid

Tools Required: Transmission fluid pump, wrench set, drain pan
Place the drain pan under the transmission pan and remove the drain plug (if equipped) to drain the fluid completely.
Remove the transmission pan by loosening the bolts in a crisscross pattern to avoid warping.
Clean the mating surface of the transmission and the pan thoroughly.
Replace the transmission filter if applicable, ensuring the new filter is seated correctly.

4. Install New Gasket and Pan

Apply a new gasket (or RTV sealant if specified) to the pan.
Reinstall the transmission pan and torque the bolts to manufacturer specifications in a crisscross pattern.

5. Refill Transmission Fluid

Using a transmission fluid pump, refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.
Start the engine and let it idle, then cycle through the gears to circulate the fluid.
