There are not many differences between the gearboxes, which have been used over the years. Gear reductions in cars with 600 cc engines are almost similar. The most important difference between older gearbox types and the ones used after 1982 is that the earlier models are all equipped with drum brakes. Although not directly related to the gearbox itself, it is a vital point.
Look for the following when checking out a gearbox:
· When shifting gear, no creaking sounds are to be heard. The synchromesh rings of the second and third gear are the first ones to wear out, resulting in a sawing kind of noise when engaging either one of these gears.
· The first gear is not synchronised and will therefore always be noisy when engaged, unless the car is at a complete stand still.
Driving a 2CV or Dyane in reverse with too great a speed may result in the locking of the gearbox. It will have to be opened up to correct the problem. This is a highly specialised task.
