Transmission Management Computer
The ATS Co-Pilot® upgrade kit for the Allison 1000 transmission solves the major problems with the stock Allison LCT-1000. When you turn up the power of the Duramax, the stock Allison 1000 transmission begins to slip in 5th gear, and the factory single-disc torque converter lockup clutch begins to slip.
The Slippage causes the Allison 1000 transmission computer to
send a "De-Fuel" signal to the engine computer causing lower and lower power
output. When the transmission is allowed to slip excessively, the
transmission will go into "Fail-safe" mode disengaging completely.
ATS's Co-Pilot upgrade kit for the Allison includes all the components necessary to increase the torque capacity of the stock transmission by approximately 200 foot pounds of torque. This kit makes it possible to transfer 100% of the power developed by a modified engine to the rear wheels without causing the dreaded transmission slip and fail safe condition that plagues the Allison transmission. This kit allows the transmissions clutch packs to receive full line pressure (clamping force needed to apply the clutches) during high power situations. The stock Allison LCT-1000/2000 and 2400 transmissions torque capacity has been reduced by limiting the 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. By allowing the available line pressure to the clutch packs we have designed a system that increases the torque capacity of the Allison transmission by over 200 foot pounds of torque with the simple addition of the Co-Pilot transmission kit. When the ATS pump kit and connverter (part of the Triple-Pack upgrade kit) is installed in addition to the Co-Pilot the clutch pack pressures are around 290 psi during high power conditions. This is a 170% hydraulic increase in torque capacity. This increased pressure is only in effect during high engine torque output, unlike other mechanical kits that do not use electronic controls. This removes the concern of excessive pressure on vital transmission parts such as delivery rings, drums, shafts, etc. during normal operation. There were great concerns during development of this kit to ensure long transmission life along with great performance. If more holding force is needed beyond what this kit supplies, the Five Star ™Torque Converter can be added.
Co-Pilot kit includes: Valve body kit with auxiliary valve body, additional solenoid, wiring harness, & transmission controller.
