mmmm, no, they don't....unless Traxxas redesigned them lately. It really just monitors the transmission movement and controls the reverse servo so you don't reverse it on the fly.
It also indicates low RX battery voltage, but does nothing about it.

OptiDrive® Electronically Controlled Transmission
Revo’s transmission delivers innovative two-speed, forward/reverse operation in an ultra-compact package. The OptiDrive electronic shift module uses advanced microprocessor control to sense vehicle speed and optimize forward and reverse shifting. Direction control is performed via a third channel on the transmitter. This revolutionary, patent-pending system allows the transmission to be lighter with fewer moving parts for reduced inertial mass and greater torque handling. OptiDrive provides constant drive engagement for seamless, responsive acceleration. The wide ratio, adjustable two-speed transmission provides no-compromise acceleration and unmatched top speed in one package.
