I have a LQ9 with a 4l65e transmission from a 2005 GMC Sierra which I´m installing in to a Suzuki truck, Is it possible to wire a switch to the pcm to engage the torque clutch converter manually? This car will mostly been driven in heavy snow conditions, so manual control of the tcc would be an awesome feature.
Has no one done it before?
Would it be a bad idea to wire up the "performance" switch to J1-71 and alter the table for performance mode to engage the TCC at all times in 2, 3 and 4th gear (no table for 1st)?
If it's a vehicle with a T42, I believe you need to send the request via CAN.
No T42, transmission is connected directly to the ecm
