I'm installing/adapting a 2004 5.3ltr w/matching 4L60E trans into a 57' Chevy Nomad and my question is: Do I need to wire in the Transmission Range Switch Connector to the PCM for it to be able to shift/operate fine? Or will it operate fine just using the Grey 20 Pin plug that controls the shift solenoids?
I know i have to wire Pin 33 on blue connector to brake switch...
I believe the engine calibration uses the transmission P/N switch to select the RAFIG or RAFPN idle air tables.
So, the transmission would shift fine without the range selector switch....Quote:

Do I need to wire these to the PCM or to actual switches? Or do I even need them?
The one's with the redline...:D
1)*Clutch Start Switch Signal*
2)*Park Neutral Position Switch*
3)*Back-Up Lamp Supply Voltage*
Park Neutral Position Switch sends a ground the PCM when in Park or Neutral, the rest dont need to go the the PCM (Clutch Start Switch Signal is for 6 speeds). I wired mine in thru the aftermarket shifter I have (and used the short selector shaft on the transmission, mine is a 4L80E).Quote:

Pretty much. It just adjusts the idle air for in gear and P/N (as Joe stated earlier).Quote:

Thanks a bunch slow67 & Joe...it worked...:thumb_yello:
