why does my Ram 1500 DT (2019-Present) have a delay in shifting

Solution

1. Preparation

• Gather 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. Check and Change Transmission Fluid

• Sub-steps:
  • Remove the transmission fluid dipstick and check the fluid level.
  • If fluid is low, drain the old transmission fluid using a drain pan.
  • Replace with manufacturer-recommended transmission fluid (e.g., ATF+4 for Ram trucks).
  • Refill the transmission with the correct amount of fluid. Refer to the owner's manual for capacity.

3. Inspect and Replace Transmission Filter

• Sub-steps:
  • Remove the transmission pan by unscrewing the bolts (use a torque wrench to ensure proper reinstallation).
  • Replace the transmission filter located inside the pan.
  • Clean the pan and magnet inside of debris before reassembly.

4. Test and Replace Transmission Control Module (if necessary)

• Sub-steps:
  • If error codes indicate a TCM issue, disconnect the module and inspect for damage.
  • Replace the TCM with a new unit if damage is found.
  • Reconnect wiring harness and ensure secure connections.

5. Reconnect Battery and Test Drive

• Sub-steps:
  • Reconnect the negative battery terminal.
  • Start the engine and take the vehicle for a test drive to verify that shifting operates smoothly.

Tools Required:

• OBD-II scanner
• Transmission fluid pump
• Socket set
• Torque wrench
• Multimeter
