why does my Ram 1500 DT (2019-Present) transmission shudder when accelerating

Solution

1. Preparation

• Tools Required: OBD-II scanner, fluid extraction pump, socket set, torque wrench.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent any electrical issues during repair.

2. Check and Replace Transmission Fluid

• Fluid Level Check:
  • Remove the dipstick (if applicable) or access the fill plug.
  • Use a fluid extraction pump to remove some fluid for inspection.
  • Check fluid color and smell; it should be red and not burnt.
• Fluid Replacement:
  • If fluid is contaminated, drain the transmission fluid completely using a fluid extraction pump.
  • Replace with manufacturer-recommended transmission fluid.
  • Refill the transmission with the appropriate amount of new fluid, checking levels with the dipstick.

3. Inspect and Replace Torque Converter (if necessary)

• Remove Transmission:
  • Safely lift the vehicle and support it on jack stands.
  • Remove the transmission access cover.
  • Disconnect the driveshaft and electrical connectors.
  • Unbolt the transmission from the engine and lower it.
• Inspect Torque Converter:
  • Remove the torque converter from the transmission.
  • Check for signs of wear or damage.
• Replace Torque Converter (if needed):
  • Install the new torque converter, ensuring it is properly seated.
  • Reassemble the transmission following the reverse order of removal, torque bolts to manufacturer specifications.

4. Inspect Engine and Transmission Mounts

• Check all mounts for cracks or excessive wear.
• Replace any damaged mounts to reduce vibration during acceleration.
