HYDRAMATIC 8L90 Manual
- The 8L90E transmission is a fully automatic eight speed rear wheel drive transmission that is available in both two and four wheel drive configurations. It features clutch to clutch shifting which provides eight forward and one reverse gear. It also uses a four element lockup torque converter, four planetary gear sets as well as five multiple disc and one mechanical clutch set. The 8L90 utilizes an off axis chain drive pump to maintain fluid volume and operating pressures. The externally located TCM controls the changing of gear ratios through the use of solenoids and also controls transmission line pressure through the use of a variable force motor. The TCM will also control converter clutch operation. The 8L90 has undergone some parts changes from its inception until the present. Some of those changes are indicated in this manual and some are not.
This manual will address the disassembly and assembly procedures for the 8L90 and is intended for use by the professional technician.
