| Predecessor | 4T60-E/4T65-E 4T80-E AX4N |
| Class | 6-speed transverse automatic transmission |
General Motors and Ford Motor Company cooperated in 2002 to create a new automatic transaxle, designed for transverse engine applications in cars and light trucks. The companies jointly committed to investing US$720 million in their manufacturing plants to support the new transmission.
Each company will name and manufacture the transmission separately:
- Ford will build the 6F at their Van Dyke Transmission Plant in Sterling Heights, Michigan, and in the future at Sharonville Transmission in Sharonville, Ohio.
- GM builds the 6T70 and 6T75 at Warren Transmission in Warren, Michigan with production starting in July, 2006.[1]
Ford claims the 6F is designed to handle 300 hp (224 kW) and 280 ft·lbf (380 N·m), while General Motors rates their 6T70 to 315 hp (235 kW) and 280 lb·ft (380 N·m) and the 6T75 to 315 hp (235 kW) and 300 lb·ft (407 N·m).
The first application of the technology is in the 2007 Ford Edge and Lincoln MKX crossover SUVs, as well as the Saturn Aura sedan and the Saturn Outlook crossover. It was also used for the Pontiac G6 GTP models and the GMC Acadia models for 2007.
