Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, fluid catch pan, shop rags.
Raise the vehicle using a jack and secure it on jack stands.
Place a fluid catch pan under the transmission to collect any escaping fluid during repair.

2. Identify the Leak Source

Inspect Transmission Pan:
- Remove the bolts securing the transmission pan using a socket.
- Carefully lower the pan and inspect the gasket for wear or damage.
Check Cooler Lines:
- Inspect the transmission cooler lines for any cracks, corrosion, or loose fittings.
- Tighten any loose connections or replace damaged lines.

3. Repair or Replace Components

Replace Gasket:
- If the gasket is damaged, clean the mating surfaces of the transmission and pan thoroughly.
- Apply a new gasket or RTV sealant as per manufacturer specifications.
- Reattach the transmission pan and torque bolts to the manufacturer's specifications (typically around 10-12 ft-lbs).
Replace Transmission Cooler Lines (if needed):
- Disconnect the cooler lines from the transmission and radiator.
- Install new lines and ensure all connections are tight and leak-free.

4. Refill Transmission Fluid

Locate the transmission fluid fill port.
Use a funnel to refill the transmission with the correct type of fluid (consult the owner's manual for specifications).
Check the fluid level again after filling, ensuring it is within the recommended range.
