swap M57/re4

[Robbaa]

hello everyone. has anyone mounted the engine m57 with the original re4 automatic transmission and can suggest how to connect the electrics?

Depends on the vehicle it's going into. If it has the RE4 originally, retaining the TCU/ECU combination allows the RE4 to run behind any engine. I have a 1996 TD42T in front of an RE4 with the original TB45E electronics and it works well.
