GENERAL DESCRIPTION

The MSG type transmission is fully synchronized 5-speek unit with blocking ring type synchronizers and a constant
mesh type reverse gear, and the transfer mechanism is built into the rear part of the transmission assembly.
The transfer mechanism is also constant mesh gear type shifting between the 2 and 4 wheel drive mode.
Shifting the transfer gears between 'Low' and 'High' is possible during 4 wheel drive operation.
