A thud on downshift in your Range Rover, “Gearbox Fault” on the dash of your Discovery, or shudder climbing a flyover — Land Rover transmission faults need specialist diagnosis.
Land Rovers pair heavy 4×4 drivetrains with ZF automatics and transfer cases. Finding a qualified Land Rover automatic gearbox specialist near you avoids misdiagnosis and unnecessary full-unit replacement.
Precision Solutions for Every Land Rover Transmission System
We service, calibrate, and rebuild:
- ZF 8HP 8-Speed (8HP45 / 8HP70 / 8HP75): In Range Rover, Range Rover Sport, Discovery, Defender. Primary automatic.
- ZF 9HP 9-Speed (9HP48): Transverse 9-speed in Evoque and Discovery Sport.
- ZF 6HP 6-Speed (6HP26 / 6HP28): Earlier Range Rover Sport, Discovery 3/4.
We also evaluate the transfer case, rear differential, and driveline shudder versus gearbox shudder.
