3t40 4 Prong TCC Solenoid Wiring
Thursday, March 01, 2012 7:04 AM
I've been searching for this all night, hope you guys can help...

I bought a 2000 Cavalier w/ the 3t40 transmission as a winter car here in NY. Come to find out, guy that had it before me had to replace the wiring harness, but it looks like he did with a harness from an earlier model 4-speed... so it has the Automatic Tranny Inline connector instead of the 4-pin TCC solenoid connector. I cannot find the end view for the 4-pin ANYWHERE. If I had it, I could delete the Auto Tran. Inline (as its just hanging free now) and wire the TCC up (to get rid of the P1870 code I keep throwing)

Thanks for all your help (and Ik I got myself in a world of hurt with buying a car with a wrong harness)
