Step 1: Visual Inspection

• Tools Required: Flashlight
• Instructions:
  1. Check for any visible damage or disconnection in the gear linkage or shifter mechanism.
  2. Inspect the transmission fluid level and condition.
     • Locate the transmission dipstick (if applicable) and check fluid level.
     • The fluid should be a clear red or pink color and not have a burnt smell.

Step 2: Check for Error Codes

• Tools Required: OBD-II Scanner
• Instructions:
  1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
  2. Turn the ignition to the "ON" position without starting the engine.
  3. Retrieve any stored fault codes related to the transmission or shifter module.

Step 3: Inspect Transmission Fluid Level and Condition

• Tools Required: Transmission dipstick (if applicable), Fluid catch pan
• Instructions:
  1. If equipped, remove the transmission dipstick. Otherwise, locate the fill plug on the transmission.
  2. Check the transmission fluid level. Ensure the vehicle is on a level surface.
  3. Observe the color and smell of the fluid. If it is brown or has a burnt smell, it may need replacement.

Step 4: Check Gear Selector Linkage

• Tools Required: Wrench set, Screwdriver
• Instructions:
  1. Inspect the gear selector linkage between the shifter and the transmission.
  2. Ensure all connections and joints are secure and not damaged.
