Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Identify Leak Source

Tools Required: Socket set, torque wrench
If the leak is from the transmission pan:
- Remove the bolts securing the transmission pan.
- Carefully lower the pan and inspect the gasket and pan for damage.
If the leak is from the transmission lines:
- Inspect the fittings and hoses for cracks or wear.

3. Replace Damaged Gasket or Seals

Tools Required: Gasket scraper, RTV sealant
Remove the old gasket material from the transmission pan and mating surface.
Apply a new gasket or RTV sealant as specified by the manufacturer.
Reinstall the transmission pan and torque bolts to the manufacturer's specifications (typically 10-12 ft-lbs).

4. Repair or Replace Transmission Lines

Tools Required: Line wrenches, replacement transmission lines
If lines are damaged, use line wrenches to disconnect the old lines.
Install new transmission lines and ensure they are securely fastened.

5. Refill Transmission Fluid

Tools Required: Funnel, transmission fluid (specific to Ram 1500)
Locate the transmission fluid fill port.
Using a funnel, refill the transmission with the appropriate type and amount of fluid as specified in the owner’s manual.

6. Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle. Check for leaks around the transmission pan and lines.
Shift through all gears to ensure smooth operation.
