Will a ECM 7747 control the TCC and High gear switch on 700r4 without the VSS installed ?
you don't even need the ECM to controal the lock up, all you need is 12v to the transmission
Yes, I know this. But was wondering does ECM need VSS to control TCC & High gear.
Ecm does not control high gear or shifting of any kind on a 700r4. Shifting is controled by throttle valve and governor.
ECM only controls the torque convertor lockup. ECM needs input from VSS to lock up the TC.
the ECM isnt necessary to control lockup.
