Hello ,
It has a governor on the side of the transmission it has spring in it and if you change the springs
The shift points will change . Just need to know the springs to use .
Apparently the springs are colour coded.
And from what I understand, the primary adjustment is in the weights. Lighter=Later shifts, with the springs fine tuning the points. I always thought my 400 was awfully early with the stock governor, but I just got used to it.
Not sure if these are the universal spring colours in general use.
Make sure that you have a good vacuum signal to the modulator valve. A split in the rubber line at the modulator valve can cause the shift points to be too high.
