This manual is to assist you with your installation and operation of the unit. If you are installing
the unit for a customer, please pass this manual on to your customer for future reference.
Understanding the ATS Five Star Co-Pilot
The ATS Co-Pilot module commands the lock-up clutch of the torque converter along with the
exhaust brake, if equipped, to stay engaged. This allows for up to 100% of the retarding force to
be transferred in 3rd and 4th gear and the transmission oil temperature to remain low because of
little to no slippage occurring when the converter is in these selected gears. When the ATS
Valve Body is installed, you can use engine braking in the low-speed position of nearly 12 mph
in 1st or 2nd gear. Currently, exhaust brake usage can cause high temperatures in the automatic
transmission due to torque converter slippage. And only a small portion of the retarding force is
transferred through the fluid coupling of most torque converters. The Co-Pilot has been
developed to provide lock-up capability in all gears. NOTE: On Dodge transmissions the ATS
Valve Body must be installed to utilize 1st and 2nd gear lock-up capability. The factory computer
is programmed to disengage lock-up under many conditions, which inhibits the performance of
the transmission. A few of these conditions are:
Lock-up disengagement at full throttle
Lock-up disengagement at closed throttle
Delayed lock-up engagement when accelerating from a stop
Delayed lock-up engagement before desired engine temperatures are reached
Lock-up disengagement under high power output
