Diagnostic software (optional for more in-depth analysis)

Repair Instructions

Step 1: Address Diagnostic Trouble Codes

If DTCs are present: Research the codes and address them appropriately. This may involve replacing faulty sensors, solenoids, or other components.
Clear codes: After repairs, clear the codes and test drive to ensure the light does not reappear.

Step 2: Change Transmission Fluid and Filter

Drain the Transmission Fluid
- Raise the vehicle securely using jack stands.
- Locate the transmission drain plug and remove it using the correct socket.
- Allow the fluid to completely drain into a suitable container.
Replace the Transmission Filter
- Remove the transmission pan (if applicable) by loosening the bolts evenly.
- Replace the old filter with a new one, ensuring that the seal is properly seated.
Install the Transmission Pan
- Clean the mating surfaces and apply a new gasket if necessary.
- Reinstall the transmission pan, tightening the bolts to the manufacturer’s specifications using a torque wrench.
Refill Transmission Fluid
- Use a funnel to refill the transmission with the correct type and amount of fluid as specified in the owner's manual.
- Start the engine and let it run for a few minutes while checking for leaks, then recheck the fluid level and adjust as necessary.

Step 3: Reset the TCM

If you have made any repairs to the TCM or reset DTCs, you may need to reset the TCM to ensure proper operation. You can do this using the OBD-II scanner or by disconnecting the battery for a short period (10-15 minutes).

Final Steps

Test Drive: After completing the repairs, take the vehicle for a test drive to ensure that the "Transmission Service Required" light does not reappear and that shifting is smooth.
