Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, transmission fluid, and a drain pan.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid electrical shorts during the repair.

2. Check and Replace Transmission Fluid

Check Fluid Level:
- Remove the transmission dipstick (if applicable) and wipe it clean.
- Reinsert and remove the dipstick again to check the fluid level.
Drain Old Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts with a socket set and carefully lower the pan to drain the fluid.
Replace Filter:
- Remove the old transmission filter and replace it with a new one.
Refill with New Fluid:
- Reattach the transmission pan with the appropriate torque (consult manufacturer specs).
- Use a funnel to refill the transmission with new fluid through the dipstick tube.

3. Inspect and Repair Transmission Components

Inspect Linkage:
- Check the transmission linkage for proper attachment and movement.
- Adjust or replace any damaged components.
Throttle Position Sensor:
- Test the throttle position sensor with a multimeter to ensure it is functioning properly.
- Replace the sensor if it is outside manufacturer specifications.
