Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Locate the Leak

Clean the transmission area with a degreaser to remove old fluid and dirt.
Use a UV light if dye has been added to the fluid to help trace the leak.

3. Replace Damaged Components

For Cooler Lines:
1. Remove the bolts securing the cooler lines using a socket set.
2. Disconnect and replace any damaged lines with new ones.
3. Reattach and tighten the bolts to the manufacturer's specifications (typically around 15-20 ft-lbs).
For Transmission Pan:
1. Drain the transmission fluid by removing the drain plug or pan bolts.
2. Remove the transmission pan by unscrewing the bolts and gently prying it off.
3. Clean the mating surfaces thoroughly.
4. Replace the gasket or use a sealant as specified by the manufacturer.
5. Reinstall the transmission pan and torque the bolts to specification (around 10-12 ft-lbs).

4. Refill Transmission Fluid

Refill the transmission with the recommended fluid type using a funnel.
Check the fluid level with the dipstick after the initial fill and adjust as needed.

5. Final Checks

Reconnect the battery.
Start the engine and allow it to idle while checking for leaks.
Test drive the vehicle to ensure smooth shifting and to verify that the leak has been resolved.
