Solution

1. Preparation

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

2. Fluid Change

Step 1: Raise the vehicle using a jack and secure it with jack stands.
Step 2: Place a drain pan under the transmission pan.
Step 3: Remove the transmission pan bolts using a socket set and carefully lower the pan to drain the fluid.
Step 4: Remove the old transmission filter and replace it with a new one.
Step 5: Clean the transmission pan and replace the gasket with a new one.
Step 6: Reinstall the transmission pan and tighten the bolts to the manufacturer’s torque specifications (typically around 10-12 ft-lbs).

3. Fluid Replacement

Step 1: Use a funnel to refill the transmission with the correct type of fluid (consult the owner’s manual for specifications; typically, ATF+4 for Ram trucks).
Step 2: Start the engine and cycle through all gears to allow the new fluid to circulate.
Step 3: Check the fluid level with the dipstick and add more fluid if necessary to reach the proper level.

4. Test Drive

Step 1: Reconnect the battery and start the vehicle.
Step 2: Take the vehicle for a test drive to ensure smooth shifting and check for any slipping.
