Desperate and need some help please. I have a 2000 Camaro LS-1 engine and 4l60e trans installing in my nova s/w. The wiring harness is a Painless 60608 which includes the car and Fuel/Trans management harness. It has a large square connector for an external range selector on the trans. The trans does not have the switch and would entail I think a shift shaft replacement as it is longer to accommodate the switch. Painless says it must be used to work properly. Does this trans have an internal selector since it had the switch on the floor shifter in the car. Can the PCM be flashed to ignore it or does to have to do with the shifting as well as starting and bu lights. Thanks in advance. I have spent hours reading and studying but cannot get a definate answer.

 

You need the switch, there is no internal one. Maybe you could hook up the f bod style switch on the shifter?
