For the 1981 model year, a lock-up torque converter was introduced which coincided with the new EMC control of most GM cars; this version is the THM350-C, which was phased out in 1984 in GM passenger cars for the 700R4. Chevrolet/GMC trucks and vans used the THM350-C until 1986. The lock-up torque converter was unpopular with transmission builders.
Because it was based on the "X" transmissions, its gear ratios from 1-3 were the same, with the fourth being 0.67:1. The transmission featured a split-torque application for third gear as well as a lockup in the torque converter. The XT-LOD was initially abandoned in 1966, but the design began again in 1974 because of rising gas prices.
A parking pawl is a device fitted to a motor vehicle's automatic transmission that locks up the transmission when the transmission shift lever selector is placed in the Park position.
The 4L60E is the electronically commanded evolution of the Turbo-Hydramatic 700R4, originally produced in 1982. The 4L60E and 4L65E are built at Toledo Transmission in Toledo, Ohio and have also been built at Romulus Transmission in Romulus, Michigan and Ramos Arizpe, Mexico. The two transmissions cannot be differentiated from the outside.
During the 1980s, automatic transmissions with four gear ratios became increasingly common, [32] and many were equipped with lock-up torque convertors in order to improve fuel economy. Electronics began to be more commonly used to control the transmission, replacing mechanical control methods such as spring-loaded valves in the valve body.
Controlled Coupling HydraMatic and Roto HydraMatic both have the "Split Torque feature" whereby, in high gear, the torque is divided 40% through the fluid coupling and 60% through mechanical connection, which made these transmissions more efficient than any other automatics before the lock-up torque converter was used.

The hydrodynamic torque converter was largely taken over from the previous 7G-Tronic transmission. It has a torque converter lock-up clutch and a twin-turbine harmonic damper with centrifugal pendulum absorber technology. [8] The torque converter lock-up can operate in all 9 forward gears.
