Toyota A442 4 Speed

The Toyota A442 series of automatic transmissions is one of our most successful transmissions for use with manual to automatic conversions. Originally used in the 80 Series Land Cruiser as a part electronic model (pressure controlled from a throttle cable) from 08/1992 until 12/1997. This version then continued onto the 105 Series Land Cruiser behind the 1HZ diesel and 1FZ-FE petrol motors until 07/2007.

The 100 Series Land Cruiser started in 1998 with a full electronic version of the A442 behind the 1HD-FTE turbo diesel and 2UZ-FE V8 petrol. The full electronic means there is no throttle cable needed so perfect for use behind throttle by wire applications.

Both of these transmission versions are controllable by the Compushift Transmission Control System.
