BorgWarner is supplying its mini direct-acting variable force solenoid (VFS) for General Motors’ global front-wheel drive 6-speed automatic transmission program (GF6). Featured in a range of 2015 Chevrolet, Buick and GMC vehicles, BorgWarner’s mini direct-acting VFS enables improved fuel economy and shift feel. Applications exist in every major global market, including the Americas, Europe, China and South Korea.
The improved efficiency and accuracy of BorgWarner’s mini direct-acting VFS result in better fuel economy and shift feel for drivers. Shorter system calibration time, ‘drop in’ replacement and reduced development cycles also make these new solenoids a fast-to-market solution for OEMs.—Robin Kendrick, President and General Manager, BorgWarner Transmission Systems
Suited for a variety of applications, the mini direct-acting VFS offers increased accuracy and reduced leakage compared with variable bleed solenoids. Because BorgWarner’s mini direct-acting VFS is virtually insensitive to temperature and supply-side pressure variations, shift quality is improved.
All of this can be achieved with minimal revision to the existing transmission valve body, while improving customer quality perception and satisfaction, the company says.
