Trent Treloar Posted April 9, 2014 Report Share Posted April 9, 2014 I have my G4 extreme wired piggy back into my 2uzfe Land cruiser / LX470 5spd auto and its all going pretty good. I am considering wiring in the control of the lockup clutch in the torque converter to supplement the factory control. Just thinking of extending the hold conditions a little. ie holding up slight hills and light throttle around town in lower gears. Â As I understand it, the lockup clutch solenoid in the trans (SLU) is a PWM controlled piece as opposed to the gear select solenoids which are either on or off.Â According to the Toyota wiring diagrams, both + and - go back to the factory ecu,Â Question is, do I splice into both these or just the one, remembering I still wish to have the factory ecu hook in to it too.
