Driving around with the OD OFF will cause the transmission to heat up quicker and possibly overheat at higher speeds.
Our ATX is made to work with a locking Torque Converter.
Keeping the Torque Converter Clutch disabled, will cause additional friction within the Torque Converter,
that the transmission isn't desgined to work with.
This will cause added heat, and as it is, our ATXs aren't designed to remove that heat effectively.
For short periods, it is okay, but not for lengthy drives.
