6 Speed Automatic Gearbox Conversion

We can design, build or adapt virtually any component that transfers or manages power or torque between flywheel and wheel hub. Two key, and typical, components are the JE-developed 6-speed Tiptronic auto gearbox for 2.4 and 2.2 Puma engined Defender, including electronic gear shift lever and trimmed cubby box housing. Additional applications are also available for other Land Rover models (including Range Rover Classic) P.O.A.

TD5 transfer box upgrade is available which reduces engine speed by 400rpm at 70mph. This is an exchange item.

We also design and build uprated propshafts and driveshafts, and adaptor kits to allow retention of original Land Rover 4×4 systems when installing upgraded gearboxes.


Working with Range Rover Classic restoration partners, we can bring the Range Rover Classic ownership and driving experience to almost modern-day standards. JE has developed a modern-day 6-speed Tiptronic auto conversion which completely changes the way gear changes are experienced, and power transferred from standard or enhanced Rover V8s to the road.
