Tales of a 3.9 litre Tdi Bushie Ute

Bushie Gearbox

Bushie Ute has a six speed Isuzu MXA6-R gearbox as used in some Isuzu trucks. The usual gearbox fitted to the 4BD1T was a five speed MSA5S with a “dual range shift”. The dual ranges are 1.000:1 for “power” and 0.762:1 for “economy”. The six speed gearbox was introduced later to provide the same functionality as a five speed plus dual range combination, i.e. 5th in the six speed box is similar to 5th in the power range, while 6th is similar to 5th in the economy range. The MXA gearbox has a greater load capacity compared to the MSA version.
