Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather necessary tools and safety equipment, including gloves and safety glasses.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick using the appropriate tool (if applicable).
Wipe the dipstick clean and reinsert it to check the fluid level.
If the fluid is low, add the manufacturer-recommended transmission fluid as specified in the owner’s manual.
If the fluid is burnt or discolored, proceed to drain the transmission fluid completely.

3. Drain and Replace Transmission Fluid

Secure the vehicle on jack stands for safety.
Place a drain pan under the transmission fluid pan.
Remove the transmission pan bolts using a socket set, and carefully lower the pan to drain the fluid.
Replace the transmission filter (if applicable) according to manufacturer specifications.
Reinstall the transmission pan with a new gasket, tightening the bolts to the manufacturer's torque specifications.

4. Inspect and Repair Transmission Linkage

Visually inspect the transmission linkage for any signs of damage or disconnection.
If necessary, adjust or replace the linkage components to ensure proper engagement.

5. Test and Clear Error Codes

Reconnect any electrical connections that were disconnected during inspection.
Start the engine and allow it to warm up.
Use the OBD-II scanner to clear any stored error codes and test drive the vehicle to verify proper operation.
