- Inspect the fluid for contaminants and odor; if burnt, replace the filter as well.
- Refill the transmission with the correct type of fluid as specified in the owner's manual.
Tools Required: Fluid pump, container for old fluid, funnel.
Safety Warnings: Use gloves and eye protection when handling fluids.

3. Inspect and Replace Transmission Control Module (if necessary)

Sub-steps:
- Remove the TCM from its housing (refer to service manual for specific disassembly instructions).
- Inspect connectors for corrosion or damage.
- If faulty, replace with a new TCM and reassemble.
Tools Required: Screwdrivers, socket set.
Safety Warnings: Ensure the vehicle battery is disconnected before working on electrical components.

4. Test Throttle Position Sensor

Sub-steps:
- Locate the throttle position sensor and disconnect the wiring harness.
- Use a multimeter to measure resistance and verify it meets manufacturer specifications.
- Replace the throttle position sensor if readings are out of range.
Tools Required: Multimeter, socket set.
Safety Warnings: Disconnect the battery before working on electrical systems.
