Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and turn off the engine.
Allow the vehicle to cool down.

2. Raise the Vehicle

Use a jack to lift the front of the Ram 1500 and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Locate the Leak

Inspect the transmission pan and gasket for cracks or wear.
Check the transmission cooler lines for leaks.
If the leak is from a seal, identify which seal needs replacement.

4. Replace Damaged Parts

If the transmission pan is leaking:
- Remove the bolts securing the pan using a socket set.
- Carefully lower the pan and drain any remaining fluid into a container.
- Clean the surface of the transmission and the pan.
- Replace the gasket with a new one and reattach the pan with a torque wrench set to manufacturer specifications (typically 8-12 ft-lbs).
If a seal is leaking:
- Remove the old seal using a seal puller.
- Clean the area around the seal.
- Lubricate the new seal with transmission fluid and install it.
If lines are leaking:
- Loosen the fittings on the leaky line and remove it.
- Replace with a new transmission line and secure fittings to manufacturer specifications.

5. Refill Transmission Fluid

Use a funnel to refill the transmission with the appropriate type of fluid (consult owner's manual for specifications).
Check the fluid level with the dipstick and add more fluid if necessary.
