The gearboxes on Series Land Rovers are basic in design but are very strong. All component parts are fairly easily obtained and a good DIY repair is perfectly possible. There is, however, a need for sufficient preliminary reading-up on the processes involved before attempting to dismantle the gearbox.

The basic design of the gearbox remained the same throughout Series I-III Land Rover production. Early Series I's however had a freewheel ring-pull mechanism for the then permanent four wheel drive to prevent axle wind-up on smooth surfaces. This was soon replaced with a lever selector for the now optional four wheel drive. The late Series IIA and all Series III models had an all synchromesh gearbox, instead of just having synchromesh on 3rd and 4th gears.

The transmission unit as a whole consists of three units - the main gearbox, the transfer gearbox and the four wheel drive selector unit. Each of these units can be separated from each other before working on one, or more, individually as necessary.

The March 2008 USA homepage describes the correct use of the main and transfer box levers for those new to Series Land Rovers.

The July 2008 USA homepage outlines the step by step procedure for the removal of the gearbox.
