Solution

1. Preparation

Tools Required: Socket set, torque wrench, transmission fluid, OBD-II scanner, multimeter, jack and jack stands.
Verify the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (typically near the engine).
2. Remove the dipstick and wipe it clean.
3. Reinsert and remove the dipstick again to check fluid level; add fluid if low.
4. If the fluid is dark or has a burnt smell, drain and replace it.
  - To drain, locate the transmission pan and remove the drain plug (if equipped).
  - Allow fluid to fully drain and replace the drain plug.
  - Add new transmission fluid through the dipstick tube, using the manufacturer-recommended type.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Use a jack to support the transmission slightly.
2. Remove the bolts securing the transmission mounts.
3. Inspect the mounts for cracks or excessive wear.
4. If necessary, replace with new mounts and torque bolts to manufacturer specifications.

4. Test and Replace Throttle Position Sensor

Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector and inspect for corrosion.
3. Use a multimeter to check the sensor's resistance; replace if out of specification.
4. Install the new sensor, reconnect the electrical connector, and clear any error codes.

5. Inspect Transmission Solenoids

Sub-steps:
1. Access the transmission control unit and locate the solenoids.
2. Disconnect the connector and use a multimeter to test for continuity.
3. Replace any faulty solenoids as per manufacturer guidelines.
