We are able to offer an electronic conversion kit for the Td5 Defender using the the Compushift to control it.

The compushift has the ability to make the autobox shift exactly as you want it, lock up when you want it, switch shift etc, when set up correctly it drives perfectly, just like a factory vehicle.

The conversion uses the stock Disco 2 TD5 autobox so if you are on a budget, you can get the autobox, converter, starter ring, cooler Etc from a breaker and just buy the Compushift and console from us to complete the job.

Please note that the shifter in the above photo is the upgraded Disco II shifter. The standard kit comes with this shifter.

Technical Information – 

Heavy Duty ZF Autoboxes

We are able to supply the ZF4HP22 with optional strength upgrades depending what you are doing with the vehicle, what gearing, what engine Etc.

Stage 1 upgrade

We can build the 4HP22 but fit the centre section of the box with the bigger 4HP24 internals which upgrades one of the weak links being the C1/C2 one way clutch, the 24 one is much stronger.

another part which gets upgrade is the Planetry Gearset, the solid 24 type being much stronger,


Just the centre internals are changed so the box stays the same externally. This upgrade is an additional £ 250.

Stage 2 upgrade

The box can be built with both the 4HP24 internals as above but also the 24 front end as well giving you the added strength of having the larger 24 “A” clutch, also a weak point with the larger engines,

The fitting implications of doing this is the unit is 15mm longer. This upgrade is an additional £ 500.

Torque Converter Upgrades

If you would like to upgrade your torque converter, please see more information here. Please note we would only recommend this option if you have a tuned engine.
