1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to ensure safety while working on the electrical systems.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and check fluid level; if low, add manufacturer-recommended transmission fluid.
3. If fluid is discolored or smells burnt, drain the transmission fluid completely.
4. Replace with fresh, manufacturer-specified transmission fluid.
Tools Required: Fluid pump, funnel, transmission fluid.

3. Inspect and Repair Wiring and Connectors

Sub-steps:
1. Locate the TCM and its associated wiring harness.
