  2. Remove the transmission pan and filter, replacing with a new filter.
  3. Clean the transmission pan and install a new gasket.
  4. Refill with manufacturer-recommended transmission fluid.

3. Inspect and Repair Transmission Components

Inspect the transmission solenoids for proper operation.
- Sub-steps:
  1. Remove the transmission pan if not already done.
  2. Locate and test the solenoids with a multimeter.
  3. Replace any faulty solenoids.

4. Reprogram or Replace TCM

If diagnostics indicate a TCM issue, reprogram or replace it.
- Sub-steps:
  1. Connect the vehicle to a diagnostic tool and follow the manufacturer’s instructions for reprogramming.
  2. If replacement is necessary, disconnect the battery, remove the old TCM, and install the new unit.
