I have seen Manual convertor lock up kits for auto transmissions in Toyota and Nissan 4wds. The purpose is to lock up the convertor in low gear while desending downhill, which in turn saves burning or wearing out your brakes.
I have fitted a GenIII 5.7 engine and 4L60E transmission out of a 2005 VZ Calais to my HJ60 land crusier. I was wondering if any one has fitted a convertor lockup kit to a 4L60E? Is it possible?
If I interrupt the wire from the ECU that controls the convertor lock up and run it through a change over relay that would be controlled by a remote switch, would this work? I am pretty sure the ECU signal is an earth, so the relay would just change the ecu signal for another earth.
Any feedback or ideas?
