Land Rover Part Number: THT000020 - Shift Control Solenoid
THT000020 is a shift control solenoid that operates within the ZF 4-speed automatic transmission valve block. Fitted to the valve block area beneath the transmission sump, this component receives electrical commands from the transmission control unit and actuates internal valve spools to direct hydraulic fluid to the appropriate clutch packs and bands, allowing gear engagement and timing of shifts. Faults in this solenoid can cause incorrect gear selection, delayed shifts or limp transmission behaviour; replacement restores the valve block's ability to respond to control unit commands.

Frequently Asked Questions
The THT000020 shift control solenoid controls hydraulic flow inside the ZF 4-speed automatic valve block to select and engage gears. It converts electrical signals from the transmission control unit into movement of internal valve spools that route fluid to clutch packs and bands, governing shift timing and engagement; a faulty solenoid commonly causes incorrect gear selection, delayed shifts or limp transmission behaviour.
