Introduction
We supply fully reconditioned manual gearboxes and transfer boxes from stock.
This section also includes a range of gearbox Service Kits, comprising the most commonly needed parts - synchro rings, bearings, oil seals & gaskets - for a straightforward gearbox overhaul.
We have avoided listing every single component associated with manual gearboxes, because there is a point beyond which DIY gearbox repair is not longer cost-effective, and replacement with an off-the-shelf reconditioned unit would probably be cheaper. Also, since gearboxes are large and fairly complex, replacement may prove simpler in the long run. Nevertheless, if there is an item which you require that is not listed, please contact our sales department.
Gearbox Identification
To identify the type of gearbox/transfer box fitted to your Range Rover, refer to the serial number stamped on the unit itself:
4 speed.
Only one type of 4 speed manual gearbox is fitted - the LT95 unit - with integral transfer box.
5 speed.
The 5 speed gearbox, introduced in 1983, is the LT77 unit, with a serial number which begins 52A. The serial number of 5 speed boxes is stamped on the main body of the unit, on the lower right-hand side. The number begins with the identification prefix, according to the engine type, followed by the actual serial number and finally, a suffix letter; either D, E, F, G or H.
With the introduction of diesel engines in April 1986, serial numbers for the LT77 5 speed begin 53A for V8 and 54A for diesel.
In December 1991, the LT77 5 speed was replaced by the LT77S. Gearbox numbers are still 53A for V8 and 54A for VM diesel, but with the addition of 55A for Tdi engines.
The LT77S 5 speed was replaced in March 1994 by the R380 5 speed box. As before, identification numbers begin 53A and 55A for V8 and Tdi respectively, but now with a suffix ‘J’.
All 5 speed gearboxes have separate transfer boxes.
