We are using AM Super Shifters, and pushed the robot maybe a maximum of 8-12 inches on the ground on low gear last night when we tried to get it driving. Could this have blown the speed controllers?
If it just continues blinking yellow that points to a faulty PWM connection usually, check your connection and make sure the pwm cable pins are nice and lined up before inserting the cable.

Bad victors are usually very easy to diagnose due to smoke coming out of them, I've only had this happen when I was dumb and let some large metal swarf land in them.
