Re: TH 350 question
I think that port, the switch is screwed into, is third gear oil and used for "transmission spark control"

Re: TH 350 question
Might want to download the manuals and read up on your truck.
http://67-72chevytrucks.com/vboard/s...d.php?t=558016 You will find info on the TCS system and wiring diagrams as well.
