ATS Built Allison LCT-1000 6-Speed Transmission
ATS Extreme Allison Packages include proprietary modifications to the drums and pistons. We have found these modifications necessary when power goes over 700hp at the tires. In addition, the pump is also modified more extensively for increased line pressure. When coupled with the Co-Pilot (sold separately), line pressure in excess of 300 PSI is achieved – which is needed to prevent clutch slippage.

All ATS Transmissions are backed by a 5 year / 500,000 mile warranty with proven reliability at the track and on the street.
