now that i have 4.10 gears and 35" tires; my fresh built 727 shifts early; I've been through the tv cable adjustment procedure; i have all lokar hardware, and also the 'corrector' plate in my holley carburetor (not sure it does anything); i have full travel of throttle from idle to wide open, and the trans TV cable moves correspondingly..i've added slack, made it tighter, i've read all the posts here, and what lokar tech and holley tech said, and from what i've been reading, i believe i need different springs setup in the governor assembly; as its a issue with driveshaft -> vehicle mph being off w/ different gears, tires, load, etc..My shifts are good, and get firmer the harder i accelerate; but it won't hold a gear long enough to get the revs up..
so..anyone been down this avenue before? I get a shifts around 2800-3000rpms, wide open..of course if i shift manually, i get change whenever i want, but even with the TV cable maxed out (i've verified the position of the arm on the transmission) it won't shift any later..I would like it to shift around 5k, should I decide to hold the pedal to the metal..so i guess what i'm looking for is some info on changing the springs in the governor, as from what i've read in the 727 rebuilding books, this is what actually controls the mph of shifts..
You are all over the place, so I'm going to try and get this on a diagnosis track again...
Did you set up the line pressure valve correctly, with the 1-5/16" spacing before you tried to set up the 'Throttle Valve Adjustments?
Did you check the line pressure after adjustment?
(one turn will adjust throttle closed line pressure 1-2/3 PSI)
Without the correct tools, you MAY have to take the pan on and off a few times to get this correct, but it's worth the aggravation.
If you DID NOT set up the Line Pressure Adjustment before you started, you may be getting WAY too much,
Or WAY too little pressure to the governor during operation.
Virtually Every "Fast" or "Slow" shift complaint I've ever worked on started right here...
During your 'Throttle Valve' adjustments, did you use a gauge on the pressure ports so you know what the pressures are?
Do you have an idea of what the governor pressure is at idle at the governor test port?
Most people contemplating tinkering with the governor didn't even know there WAS a governor pressure test port!
Governor changes will often mean the removal of the transfer case, and that is something to think about if you haven't tested for correct pressure settings...
