I have done custom grounding on my car (fallowing irish44j excellent write up but I would like to ground my tranny also (auto) - any body have a picture of grounding point of auto tranny point? Will I benefit if I also ground my TB, headlight, A/C and starter - if yes where are the Grounding Points on those.
PS
I've tried search for Grounding Points for tranny but no luck.

 

I don't have a pic, but the tranny grounding point on an automatic is at the front of the transmission housing. put the car up on ramps, and remove the plastic underbody panels behind the bumper. Look up, right in the middle of the car, about 9" back from the bumper. There's a point where (as I recall) with bolt holding some other wires. That is the grounding point. Been a while since we did it on soonerfan's old maxima, so my memory's a bit rusty though!
