UV light (optional for dye detection)
Oil catch pan
Replacement transmission fluid
Replacement gaskets/seals (as needed)

Repair Instructions

Step 1: Prepare the Vehicle

Safety First: Park the car on a level surface, set the parking brake, and turn off the ignition.
Lift the Vehicle: Use a jack and jack stands to lift the front end of the vehicle for better access to the transmission.

Step 2: Identify and Fix the Leak

Transmission Pan Gasket Replacement:
- Drain Fluid: Place an oil catch pan under the transmission pan, remove the bolts securing the pan, and carefully lower it to drain the fluid.
- Clean Surface: Clean the mating surface on the transmission and the oil pan.
- Replace Gasket: Install a new gasket and reinstall the transmission pan. Torque the bolts to the manufacturer’s specifications.
Axle Seal Replacement:
- Remove Axle: If the axle seal is leaking, remove the axle from the transmission. This may require a slide hammer or a pry tool.
- Remove Old Seal: Use a seal puller to carefully remove the old seal.
- Install New Seal: Lubricate the new seal with transmission fluid and carefully press it into place using a seal installation tool or a suitable sized socket.
- Reinstall Axle: Reinstall the axle and ensure it is secured properly.
Transmission Cooler Line Replacement:
- Disconnect Lines: Use a wrench to disconnect the cooler lines from the transmission.
- Replace Lines: If the lines are damaged, replace them with new lines.
- Reattach Lines: Reattach the lines securely and check for tightness.
Transmission Filter Replacement (if applicable):
- Remove Pan: If you have not done this already, remove the transmission pan as described earlier.
- Replace Filter: Remove the old filter and install a new filter. Ensure it is seated correctly.
- Reinstall Pan: Reinstall the transmission pan with a new gasket as described earlier.

Step 3: Refill Transmission Fluid

Refill Fluid: Use a funnel to pour the recommended type of transmission fluid back into the transmission through the dipstick tube. Refer to the owner’s manual for the correct fluid type and capacity.
Check Level: Start the engine and allow it to run for a few minutes. Shift through all gears, and check the fluid level again, adding more fluid if necessary.

Step 4: Final Checks

Inspect for Leaks: After making repairs, check the areas where you worked for any signs of leaks.
Test Drive: Take the vehicle for a short test drive to ensure proper operation and that no leaks are present.
