Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather tools: socket set, funnel, transmission fluid, OBD-II scanner, and safety glasses.

2. Fluid Level Check

Sub-step 1: Locate the transmission dipstick (if equipped) or check the fill plug.
Sub-step 2: Remove the dipstick or plug and wipe it clean.
Sub-step 3: Reinsert and remove again to check fluid level; add fluid if low.
Sub-step 4: Inspect fluid for contamination (burnt smell or dark color).

3. Transmission Linkage Inspection

Sub-step 1: Visually inspect the transmission linkage and shift cables for wear or disconnection.
Sub-step 2: Adjust or replace linkage components as necessary to ensure proper engagement.

4. Throttle Position Sensor Test

Sub-step 1: Disconnect the electrical connector from the throttle position sensor.
Sub-step 2: Using a multimeter, measure the voltage output while manually moving the throttle.
Sub-step 3: Compare readings with manufacturer specifications; replace if out of range.

5. Fluid Change

Sub-step 1: Remove the transmission pan using a socket set and let the fluid drain completely.
Sub-step 2: Replace the transmission filter if applicable.
Sub-step 3: Reinstall the pan and torque to manufacturer specifications.
Sub-step 4: Fill the transmission with the appropriate type and amount of fluid through the dipstick or fill plug.
