1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set.
Remove the transmission pan (if needed) to access the fluid.
Drain the old transmission fluid completely.
Inspect the pan for metal shavings or debris.
Replace the transmission filter if applicable.
Refill with manufacturer-recommended transmission fluid using the pump and funnel.
Reattach the transmission pan, ensuring a proper seal is formed.

3. Inspect and Replace Transmission Range Sensor

Tools Required: Socket set, multimeter.
Locate the transmission range sensor on the transmission.
Disconnect the wiring harness from the sensor.
Using a multimeter, test the sensor for continuity and proper voltage.
If faulty, remove the sensor and install a new one, ensuring it is properly aligned.
Reconnect the wiring harness.

4. Reprogram or Replace TCM

Tools Required: OBD-II scanner, laptop with diagnostic software.
If the TCM is suspected to be faulty, use the OBD-II scanner to check for software updates.
Follow the manufacturer's instructions to reprogram the TCM if necessary.
