Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, transmission fluid pressure gauge, torque wrench, fluid catch pan.
• Safety Warnings: Ensure the vehicle is parked on a level surface and the engine is off before starting work.

2. Change Transmission Fluid and Filter

• Sub-steps:
  1. Raise the vehicle using jack stands and secure it.
  2. Place a fluid catch pan under the transmission pan.
  3. Remove the transmission pan bolts using a socket set and carefully lower the pan.
  4. Remove the old transmission filter and replace it with a new filter.
  5. Clean the transmission pan and magnet to remove any debris.
  6. Replace the pan gasket and torque the pan bolts to manufacturer specifications (check the manual for torque values).

3. Repair or Replace Faulty Components

• Sub-steps:
  1. If error codes indicate a faulty TCM, disconnect the battery and remove the TCM from its mounting.
  2. Replace with a new TCM if necessary and reconnect all wiring.
  3. If transmission fluid pressure is low, inspect and replace any damaged seals or solenoids as needed.

4. Refill Transmission Fluid

• Sub-steps:
  1. Use a funnel to refill the transmission with the recommended fluid type, ensuring it reaches the correct level.
  2. Start the engine and cycle through all gears to allow fluid to circulate, then recheck the fluid level and adjust as needed.
