Introduction Automatic Transmission Automatic transmission was introduced as an option for the Range Rover in August 1982. The first auto box fitted was the 3-speed Chrysler Torqueflite A727 unit. This gearbox was used until September 1985, when it was replaced with the ZF 4HP22 4-speed box. The ZF box remained until the end of Classic Range Rover production. Serial Number Location The ZF 4sp gearbox has a plate bearing the serial number attached to the lower left hand side of the gearbox casing, visible from beneath the vehicle.
