ATS 6019244368 Co-Pilot Transmission Controller

The ATS 6019244368 Co-Pilot Transmission Controller makes it possible to transfer increased power levels to the rear wheels in your 2011-2016 GM 6.6L Duramax without causing the dreaded transmission slip and "limp mode" condition that plagues the Allison transmission. The Co-Pilot package alone, without any internal transmission modifications, allows the transmission to handle approximately 85 more horsepower and 120 foot pounds of torque over the power level at which the stock Allison will typically enter into "Fail Safe" mode, roughly 425HP/650Tq. 

The Co-Pilot kit allows the transmissions clutch packs to receive full line pressure (clamping force needed to apply clutches) during high power situations. The stock Allison transmissions torque capacity has been reduced by the limited pressure that is available in the clutch packs. The stock Allison transmission only receives approximately 86-PSI oil pressure to the clutch packs when in 5th gear. After the addition of the Co-Pilot transmission system the transmission clutch packs receive approximately 230-PSI, more than 2.5 times the stock pressure.
