- Aisin: The Aisin 6-speed automatic is one of the transmissions available with Ram’s 6.7L Cummins turbo-diesel engine. This engine produces up to 400 hp and 1,000 lb-ft of clean-diesel torque. With the Aisin transmission, it can tow 31,000 pounds.
- The Ford 6R80 transmission is an impressively strong, band free, 6 speed automatic transmission modeled after the renowned and respectable ZF 6HP26 six speed automatic transmission. The 6R80 was first introduced in 2009 and is manufactured under ZF license at the Ford Transmission Plant in Livonia, Michigan.
General Motors and Ford Motor Company cooperated in 2002 to create a new automatictransaxle, designed for transverse engine applications in cars. 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 builds the 6F50 and 6F55 along with the 6F35 (related to the GM 6T40 transmission) at their Van Dyke Transmission Plant in Sterling Heights, Michigan, and in the future at Sharonville Transmission in Sharonville, Ohio.
- GM builds the 6T70, 6T75 and 6T80 at Warren Transmission in Warren, Michigan with production starting in July 2006.[1]
Ford claims the 6F50 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), the 6T75 to 315 hp (235 kW) and 300 lb⋅ft (407 N⋅m), and the 6T80 to 410 hp (306 kW) and 369 lb⋅ft (500 N⋅m). GM lists the wet (with fluids) weight of the 6T70/75/80 to be between 102 kg (225 lb) and 104.7 kg (231 lb).
6-speed Automatic Transmission With Shiftronic
Ford appears not to have made a public statement regarding the 6F55's maximum capabilities, but uses it in AWD in the Taurus SHO with an engine rated at 272 kW (370 PS; 365 hp) and 475 N·m (350 lb·ft) of torque (Final drive 2.77:1 standard or 3.16:1 with SHO Performance Pckage), as well as the tenth generation Lincoln Continental with an engine rated at 400 hp (298 kW; 406 PS) and 400 lb⋅ft (542 N⋅m).
The first application of the technology is in the 2007 Ford Edge and Lincoln MKXcrossover 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. Prior to 2009, this transmission had issues caused by a very weak 3,5,R wave plate, which made this transmission prone to failure in GM products. Updated wave plates were released for many clutches in 6T70. The old design wave plates weren’t stress relieved and could break with use. The updated wave plates are available under the followingpart numbers:
| Clutch | Part Number |
|---|---|
| 1234 | 24259063 |
| 2-6 | 24259816 |
| 3-5-Rev | 24254103 |
| Low-Rev | 24259817 |
