Screwdrivers (flathead and Phillips)
Transmission fluid (as specified in the owner's manual)
Shop towels or rags
Flashlight
Transmission sealant (if needed)

Repair Instructions

Step 1: Raise the Vehicle

Safety First: Ensure the vehicle is on a flat surface.
Jack Up the Vehicle: Use a jack to lift the car and place it securely on jack stands or drive it up on ramps.

Step 2: Identify the Leak Source

Inspect: Check the transmission pan for any cracks or loose bolts.
Examine Seals: Inspect the front and rear transmission seals, as well as the cooler lines for signs of leakage.
Check the Gasket: If the gasket is damaged, it will need to be replaced.

Step 3: Repair the Leak

Transmission Pan Gasket Replacement:
- Remove the Transmission Pan: Use a socket set to remove the bolts holding the pan in place. Allow any fluid to drain into an oil catch pan.
- Clean Surfaces: Use a gasket scraper to clean the mating surfaces of the transmission and the pan.
- Replace the Gasket: Install a new gasket and reattach the pan using a torque wrench to the manufacturer’s specifications.
Seal Replacement:
- Remove Old Seals: Use a seal puller to remove the old front or rear seals.
- Install New Seals: Lubricate the new seals with a bit of transmission fluid and press them into place carefully.
Tighten Cooler Lines:
- Inspect and tighten any loose connections on the cooler lines. If the lines are damaged, they will need to be replaced.

Step 4: Refill the Transmission Fluid

Fill Fluid: Using a funnel, refill the transmission with the correct type and amount of fluid as specified in the owner's manual.
Check Level: Start the engine, let it run for a few minutes, and shift through the gears. Recheck the fluid level and add more if necessary.

Step 5: Test Drive

Road Test: Take the vehicle for a short test drive to ensure proper operation and check for any further leaks.
Recheck for Leaks: After the test drive, inspect again for leaks.

Conclusion

If the leak persists even after these repairs, or if you are unable to identify the source, it may be time to consult with a professional mechanic or take the vehicle to an authorized Toyota service center for further diagnosis and repair. Regular maintenance and monitoring of transmission fluid levels can prevent future leaks and ensure the longevity of your vehicle's transmission system.
