Eight Speed Transmission

Back to article View Gallery
4 of 9
The 8HP45 (V-6) and 8HP70 eight-speed transmissions offer a wide range of gearing from 4.7:1 (1st) to 0.67:1 (8th). These transmissions have four gear sets and five shift elements (clutches/brakes), but only two shift elements are engaged at any one time. The unit has been purposely designed to offer the wide range of gearing, yet does so in a very efficient manner to maximize fuel economy.
