I'm doing a stand alone swap of an 2001 5.3 / 4L60E out of a Silverado. Reviewing the differences between truck and F-body 4L60E transmission connections, it appears that the truck transmission uses two Park/ Neutral Posisition Switches while the F-body does not. Along these same lines, the F-body, I have read only requires 1 ground wire to indicate that the car is in Park/Neutral (C1 (blue) 34). What has me a little bit puzzled, is why does the truck need the extra wires. Looking at the connector listing (I only have a copy of the pin out - no schematic) ... the 2 PNP switches for the truck show things like
- Transmission Position Switch Signal (A, B, C and P)
- Netural Safety Switch Park Signal
- Back-up Lamp Supply Voltage
- Neutral Saftery Switch Park/Neutral
Some questions that I started to ponder ....
- So for a truck OS, these connectors are used to trigger the back up lights while in reverse? Would guess through the BCM?
- is this the park / netural safety switch for starting?
Reason for asking is that I am considering using the F-body OS. I have documented the pin out differences for the PCM, just not quite sure about how things will operate. If you happen to have a schematic of the transmission, back up lights, or starting circuits that you could share that would be great. It would be nice if these connectors could be used as is for the back up lights and neutral/park saftey switch.
Thanks,
Darren
