Victoria the Land Rover

Gearbox SIIA spec.

From the Resto-Mod department

Victoria received a refurbished gearbox and transfer case from ACR in 2009.

The original 4-speed gearbox fitted to the Land Rover Series IIA was a robust and straightforward unit, designed for durability and off-road capability rather than refinement.

Gear shifting is mechanical and requires deliberate action, especially in early models without full synchromesh. Known for its "agricultural" feel—rugged but not refined.

Non-synchronized (crash) first and second gears; synchromesh on 3rd and 4th gears only. Double-declutch is a must when shiffting down from 3rd to 2nd, for example when heading down a hill, in need of engine break. The 2nd gear would not engage if not handle properly ! I have experienced people who even could not simply shift upwards from the 1st gear to the 2nd... It is sporty !

Typical ratios for the Series IIA gearbox provide good torque for off-road use, especially when combined with the two-speed transfer box.

>Black lever knob: usual manual transmission, 4 forward gears and 1 reverse.
1st gear: ~3.6:1
2nd gear: ~2.2:1
3rd gear: ~1.4:1
4th gear: 1:1 (direct drive)
Reverse: ~3.8:1

>Red knob lever moves the Transfer Box: mounted aside the main gearbox, it offers High and Low range gearing on all gears.

>Yellow lever knob: selectable 4WD system in low range and high range too.

Series IIA gearboxes (D suffix & later) are generally considered to be stronger and longer lasting than early series III gearboxes. Though a lot of this conception may have to do with people’s shifting habits. Series III boxes prefer that you hesitate briefly in the neutral position while you shift gears. This puts less stress on the syncros and enhances their service life.
