4. Repair or Replace Transmission Components

If leaks are found, replace the faulty seals or gaskets.
If the fluid is burnt or contaminated, consider a complete fluid change and filter replacement.
If the shift linkage is found to be damaged or disconnected, repair or replace it as necessary.

5. Reassemble and Test

Reinstall any components removed during inspection and ensure all connections are secure.
Lower the vehicle and start the engine.
Test drive the vehicle to confirm proper operation of the transmission.
