FYI trany governor weights

If your new to all this, like me, some info on what to expect.
Had the car out to the track with the kick down cable hooked up. Shifted at 4500 rpm @ WOT. Studied the governor
and how to change weights.
From what I read it sounded like the larger weights were independent of the smaller, and controlled low speed only.
Here's one thing I read:
There are two sets of rotating weights in the governor. The heavier, outer weights act at low vehicle speed and the lighter inner weights take over at higher speeds, especially during full throttle conditions. Centrifugal force acting upon the weights controls the opening and closing of the governor valve itself. The valve controls governor pressure delivery, which in turn controls upshifts.

When there is enough centrifugal force upon the weights to open the valve, line governor pressure overrides the shift valve spring, and the shift occurs. Changing the inner weights on the governor allows you to adjust the rate of this line pressure versus vehicle speed balancing act, and optimize full throttle shift points to your vehicles power to weight ratio, rear end gear ratio, and so on.


Thats not the case, my impression was wrong, both weights control one valve and are cumulative. I went down 4G. on the inner weight, which
raised the shift point to 5000 rpm, gained .8 on my time.
How ever when idling around on the flats, between 1200
rpm and 1500 rpm, the governor "hunts", like a hit n miss engine.
After next week, I'm going to a smaller cam and reinstall the stock weights, until next year.

B&M sells a "Governor Recalibration Kit" that has 6 different inner weights, 6 inner springs and has new axle pins with e-clips on them...this kit allows you to tailor both ends of the shift spectrum.

TCI has one also.

A spring rate change may be all you need to eliminate the low rpm hunting

I do have the TCI kit, but the new cam will be for low end
torque. Thats how the governor was set up before.
Thanks
