3.2.1.13. Mechanical five-speed transmission of MT 75 type

GENERAL INFORMATION

Since November, 1988 in Ford Sierra cars with diesel engines instead of a mechanical five-speed transmission of type N the mechanical five-speed transmission of MT 75 type is established.

The transmission three-gross, a classical design has five synchronized transfers for advance (the 4th transfer – a straight line) and the synchronized transfer of a backing. The box is established along a car axis behind the engine. The lever of gear shifting is established on a car floor.

Transfer numbers

1	3,65	3,62	13,21
2	1,97		7,13
3	1,37		4,96
4	1,00		3,62
5	0,82		2,97
Backing	3,66		13,25
