I am pulling the engine and trans out of a 71 Riviera. I noticed the kickdown plug was a double plug. I had heard that a TH400 with a double kickdown plug was a switch pitch. I had also heard that switch pitches were not made after 1967. What did I pull out of the Riv? Thanks. Craig
OK, I figures it out. The extra wire is for the TCS solenoid. It's just a run of the mill TH400. Carmak
