Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, and replacement transmission filter if necessary.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Replace Transmission Fluid

Sub-step 1: Remove the transmission dipstick (if equipped) and check the fluid level; add fluid as needed to reach the proper level.
Sub-step 2: If the fluid is low or burnt, drain the old transmission fluid using a suitable container.
Sub-step 3: Replace with the recommended type of transmission fluid (check owner's manual for specifications).
Sub-step 4: Reinstall the dipstick and run the engine to circulate the new fluid, checking for leaks.

3. Replace Transmission Filter

Sub-step 1: Locate the transmission pan; remove the bolts using a socket set and gently lower the pan to avoid spilling fluid.
Sub-step 2: Remove the old transmission filter and replace it with a new one, ensuring it is seated properly.
Sub-step 3: Clean the pan and replace the pan gasket if necessary before reinstalling the pan with the specified torque.

4. Inspect and Test Electrical Components

Sub-step 1: Check the TCM for proper connections and inspect wiring for any signs of wear or damage.
Sub-step 2: If issues persist, test the TCM using a specialized automotive multimeter to ensure it is functioning within specifications.
