To adjust the valves on the SDLG LG918, follow these steps:

1. Check the Converter Pressure: Inspect the pressure of the pressure-regulator valve in the transmission charging pump. If necessary, replace it.

2. Readjust to Specified Value: Ensure that every gear's control valve is set to the correct pressure.

3. Replace Faulty Components: If the pressure-regulator valve spring is invalid, change the spring in the transmission control valve regulator.

4. Disassemble and Inspect: If the pressure-regulator valve or lock accumulator piston is locked, disassemble and check the transmission control valve.

These steps help maintain proper valve function and ensure efficient operation.
