C6 Shift point adjustment - Ford Muscle Forums : Ford Muscle Cars Tech Forum

tbird · 08-10-2002, 03:57 AM

I want to adjust my C6 so it shifts
at a higher RPM while in drive.
I run better ET's when I spin the motor
higher. And I run more consistent when I let
the trans shift on its own.

What controls the shifting points.
I think its the governor but I am not positive.

What do I have to do to change the shift
points.

Check if your tranny has an adjustable vacuum modulator. Pull off the vacuum line and look in the hole. If there is what looks like the head of a small screw in there, it's adjustable. Use a tiny flat screwdriver and turn it clockwise to raise the shift points. It's not reccomended that you go more than 6 turns from the stock position however. If your tranny doesn't have an ajustable vacuum modulator, buy one for it. They're not hard to find, plus they are cheap, and easy to change.

Going good, hey there is a jet question for you at gofast under engine forum if you get a chance would you look at it? I also would like to know how to change the shift piont on mine.Mine shifts at 5000 rpm's (wot) with the cheeta valvebody.So I put a pro rachet in.
