Solution

1. Preparation

Tools Required: Safety gloves, safety glasses, transmission fluid dipstick, OBD-II scanner, socket set, torque wrench.
Ensure the vehicle is on a level surface and the engine is turned off before beginning any work.

2. Inspect and Change Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check the fluid level. It should be between the "Full" and "Add" marks.
2. If the fluid is low or burnt, prepare to change it by gathering the necessary tools and replacement fluid.
3. Place a drain pan under the transmission pan, remove the transmission pan bolts, and carefully drop the pan.
4. Allow the old fluid to drain completely, then inspect the pan for metal shavings or debris.
5. Replace the transmission filter if applicable, ensuring it is seated properly.
6. Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer's specifications.
7. Fill the transmission with the recommended fluid type (usually ATF+4 for Ram trucks) to the correct level.

3. Inspect and Replace Bearings (if necessary)

Sub-steps:
1. If the whining persists after fluid change, prepare to investigate internal components by removing the transmission.
2. Disconnect the battery and drain the transmission fluid again.
3. Remove components connected to the transmission (driveshaft, electrical connectors, etc.).
4. Unbolt the transmission from the engine and carefully lower it from the vehicle.
5. Inspect the input and output shaft bearings for wear or damage.
6. If bearings are worn, replace them. Ensure to clean all surfaces and apply assembly lubricant before reinstallation.
