Client goal
Convert an original Defender TD5 to automatic while keeping the wiring professional, serviceable and suitable for refinement. The interior also needed a custom centre console solution to suit the automatic selector and upgraded cabin layout.
The brief
Integrate the automatic gearbox wiring into the original Defender harness, make sure the transmission controller received the required engine data, support gearbox software tuning and help develop the custom centre console package.
Scope of work
Key systems
Engineering challenge
Practical outcome
The automatic conversion was electrically integrated and then tested so the gearbox could be refined. The centre console development also created a more complete interior solution that could be adapted for 90 and 110 Defender builds.
For similar clients
This project is relevant for Defender owners who want modern usability without a full EV conversion. It also shows how wiring, transmission control, interior packaging and repeatable product development can be handled together.
