EV Automatic Gearbox Controller Project
 
Thought I'd start a thread on a new project I have just begun. Plan is to develop an open source arduino based controller for automatics. The ZF 5HP24 is my first victim as I need it for a new conversion project but also plan on looking at the 5HP18 and the CAN bus controlled 6HP26.

First installment is a general intro and look at the flexplate coupler design :

Part 2 : Looking at the range switch and working out basic software to control the valves.

very cool, do you forsee doing away with the torque converter before it is all sorted out?

The efficiency curve is my main reason for asking...

More work on the adapter plate. Now finished and ready to be mated to the gearbox. Just hope the damn thing fits ....

wow! that trans is massive next to the motor. Do you already have some idea what the electrical pins do for controlling it?

Why not just use direct drive and eliminate losses?
