Gearbox Controller v1 

Maximum sustained current of 3amps (4amps peak for 5 seconds) - Silent relay free operation

2m loom included (Possible to switch to 3m and 4m options by purchasing these options seperately, also possible to purchase DIY screw terminal plug seperately)

Due to current low production volumes the case is 3d printed, but this does allow some flexibility. Should you require a custom case with different mounting points this should be possible for a small extra cost, please contact us here.

This has been extensively tested on a Ford A4LD gearbox, but it should also work with any model such as the Dodge/Chrylser A518 RH that uses grounding of solenoids as the method to activate the lockup and/or overdrive.

Any speed sensor that provides a regular 12v pulse should work, but here are a few aftermarket options that would work:
- Inline Speedo Sensor or here
- Alternative Inline Speedo Sensor
- Another Alternative Inline Speedo Sensor

Any 3 wire potentiometer style thottle sensor should work, but here are a few options that would work:
- Full kit including plug/short wires
- Alternative full kit including plug/short wires
- 6 wire sensor (Nissan X-Trail)
- 3 Wire sensor (Mazda 6) 
It's worth noting you'll also need to source a plug to match the 3rd and 4th options. A useful reference for wiring up a wide variety of throttle sensors can be found here.
