Ok gentlemen, I've got a trans issue here.
Brand new ATS Stage 6 (I know, I know) behind a fresh built 6.4
Less than 200 miles on it, and now it will not downshift at a stop in drive. If I come to a stop and manually shift to first it will engage and I shift right back to drive.
So I broke out the ATSG manual, and it suggests gov solinoid and transducer are faulty.
Hooked a manual pressure guage up to the governor port.
ATSG says if pressure is 0 in drive, then a servo is stuck.
And if pressure is 7-12psi then the gov solinoid or transducer is at fault....
Ok easy enough, right ?
So I hook up the pressure guage, start the truck and put it into Drive.
Pressure is "average" at 120psi. And I say average because the needle is bouncing wildly between 105 and 135.
Any guidance would be appreciated.
