2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it to check fluid level.
2. If fluid is low, add manufacturer-recommended transmission fluid until the correct level is reached.
3. If fluid is discolored or burnt, proceed with a complete fluid change.
4. To change fluid, drain the transmission pan by removing the drain plug (if equipped) or pan bolts.
5. Replace the transmission filter if applicable.
6. Reinstall the pan, torque bolts to manufacturer specifications (usually around 8-10 ft-lbs).
7. Fill the transmission with the correct fluid type through the dipstick tube.

3. Inspect and Replace Transmission Range Sensor

Sub-steps:
1. Locate the transmission range sensor on the transmission.
2. Disconnect the wiring harness from the range sensor.
3. Remove the bolts securing the sensor and carefully take it out.
4. Install the new sensor and secure it with bolts, torquing them to specifications.
5. Reconnect the wiring harness.

4. Inspect and Replace Transmission Mounts (if necessary)

Sub-steps:
1. Inspect the transmission mount for cracks or excessive wear.
2. If damaged, remove the bolts securing the mount to the transmission and the frame.
3. Replace the old mount with a new one, ensuring proper alignment.
4. Torque the mounting bolts to specifications.
