Discovery 1 Manual Gearbox Gearlever Housing Kit
Gearlever housing kits contain parts which are prone to wear, resulting in vague gear selection.
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 no longer cost-effective, and replacement with an off-the-shelf reconditioned unit would almost certainly 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.
To identify the type of gearbox/transfer box fitted to your Discovery, refer to the serial number stamped on the unit itself:
The 5-sp gearbox fitted to Discovery is either the LT77 unit or the R380, which replaced the LT77 in 1994.
Both types of gearbox have identification numbers according to which engine they mate to, as follows:
57A - V8 carb
53A - V8 efi
55A - Tdi
59A - 2.0 Mpi
Then follows the serial number and finally, a suffix letter: D, E, F, G or H for LT77 and I, J, & K for R380.
All gearboxes have separate LT230T transfer boxes.
