Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Safety gear: gloves and safety glasses.

2. Clean the Area

Wipe down the transmission case and surrounding areas with a clean rag to remove old fluid and debris.
Inspect for any wet spots or stains that could indicate a leak.

3. Inspect Transmission Pan and Gaskets

Tools Required: Socket set, torque wrench
Remove the transmission pan bolts using the socket set.
Carefully lower the pan and inspect the gasket for any signs of wear or damage.
If the gasket is damaged, replace it with a new one.
Reinstall the pan and torque the bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs).

4. Check Transmission Cooler Lines

Tools Required: Wrench set
Follow the cooler lines from the transmission to the radiator.
Check both ends of the lines for tightness and signs of wear or corrosion.
If any leaks are detected, replace the damaged line or tighten the fitting.

5. Inspect Seals

Tools Required: Screwdriver set, pry bar (if necessary)
Check the input and output shaft seals for signs of leakage.
If any seals are leaking, carefully remove the old seals using a screwdriver or pry bar.
Install new seals ensuring they are properly seated.

6. Refill Transmission Fluid

Tools Required: Funnel
After all inspections and repairs, refill the transmission with the appropriate type of fluid as specified in the owner’s manual (typically Mopar ATF+4).
Use a funnel to avoid spills, and ensure the fluid level is correct.
