my Skoda Octavia NFL (2020-Present) won't shift into reverse what could be wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and engage the parking brake.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick or fill plug and check the fluid level.
   • If low, top up with the manufacturer-recommended transmission fluid (check owner's manual for specifications).
   • If dirty, plan for a fluid change.
3. To change the fluid, drain the transmission pan by removing the drain plug.
4. Replace the transmission filter if applicable.
5. Refill the transmission with the new fluid through the dipstick tube or fill plug.

3. Adjust or Replace Shifter Linkage

1. Locate the shifter linkage under the vehicle.
2. Inspect for any signs of wear or misalignment.
3. If misaligned, adjust the linkage according to the manufacturer's specifications.
4. If damaged, remove the old linkage and install the new one.
   • Use appropriate fasteners and torque settings as specified in the service manual.

4. Inspect Transmission Control Module (TCM)

1. Locate the TCM, typically found near the transmission.
2. Visually inspect for corrosion, loose connectors, or damaged wiring.
3. If damage is found, repair or replace the affected components.
4. Reconnect all wiring and ensure secure connections.
