Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, replacement transmission filter (if necessary), torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool if it has been running.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level and condition.
If the fluid is low, add the recommended transmission fluid type (check the owner's manual for specifications).
If the fluid is burnt or contaminated, proceed to drain the transmission fluid:
- Place a pan underneath the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan and allow the fluid to drain completely.
Replace the transmission filter (if applicable) by removing it from the transmission body.
Reinstall the transmission pan with a new gasket, torque the bolts to manufacturer specifications (usually around 10-12 Nm, refer to service manual).
Refill the transmission with new fluid through the dipstick tube.

3. Inspect and Test Transmission Components

Using a multimeter, test the TCM for proper voltage and functionality, following the specific testing procedures outlined in the service manual.
Inspect the transmission solenoids for signs of failure; replace if necessary.
Check the engine and transmission mounts for any damage; replace mounts if they show signs of wear or separation.
