Automatic trans shifting

One huge problem with using the governor to control shifts is that not all race engines require the same RPM at every shift for both performance and consistency.

I worked hard on a Ford C-4 to get the shift points where We wanted them and it worked well. After many passes the converter failed so to save time and get back racing I installed a manual valvebody trans. off the shelf and raced it. I was just as consistent manually shifting as the automatic shifting of the other unit. I now have the auto shift back so I can pay attention to other aspects but consistency was not a big difference. My combo has a pretty big window to shift, some could be more sensitive.
