That black button sucks for sure, until u screw w/ and finally put a pair of pliers on it, I had to use a fuel line clamp on mine afterward.
Do you have to change springs when u add a higher shifting governor ???????
Not necessarily. Sometimes you do if the 1-2 and 2-3 shift points are different rpms. I haven't had issues with the shift points being very far off but A&A can send off a couple springs to try out and you just return the ones you don't need. I think the determining factor in my case is the shift kit. It adds another variable as the increased line pressure makes the auto shift higher to begin with.
I have a 5800rpm governor in my 62 without a shift kit and it shifts perfectly on both up shifts.
