The 2.2l S10/Sonoma had the starter located in the same position as front wheel drive cars. A rear wheel drive bellhousing is displayed at right, and the integrated front wheel drive bellhousing is displayed at the lower right (in this case, as a part of the GM 6T70 Transmission). GM 60-Degree 2.8/3.1/3.4/3.5/3.9 L V6 (also used by AMC) Buick ...
The General Motors Automatic Safety Transmission (AST) was a semi-automatic transmission released in 1937. The first mass-produced fully-automatic transmission developed for passenger automobile use was the GM Hydra-Matic introduced in the autumn of 1939 as a (very likely subsidized) $57 option for the 1940 Oldsmobile.

The original version of the transmission had a 27-spline input shaft (shared with the THM200C and 2004R) which was a common failure point. In 1984, the 700R4 designed for use behind Chevrolet small block V8s received a 30-spline input shaft similar to those found on TH400 transmissions and which also used a different torque converter than its 2 ...
The two transmissions cannot be differentiated from the outside. The 4L65E shares the same exterior parts but have stronger internals such as 5 pinion planets compared to 4 in the 4L60E. 4L60E uses a 6.5" depth bell with 6 bolts for non gen 3 LS applications and a 7" depth bell with 7 bolts for LS applications.
The Automatic Safety Transmission (AST) was a tangent outgrowth of this work. The AST was a semi-automatic transmission using planetary gears and conventional friction clutch, requiring the driver to use the clutch to shift into or out of gear, but not between the two forward gears. Oldsmobile offered the AST from 1937 to 1939, while Buick ...
The basis of the Turboglide's unique abilities was its five-element torque converter.Most automatic transmissions have a three-element torque converter, consisting of an impeller (an engine-driven pump); a turbine that rotates with the flywheel; a transmission-driven turbine that receives the energy of the oil propelled by the impeller, and a stator that redirects the recirculating oil so that ...
For 1991 GM introduced the 4T60-E which was a 4T60 with electronic controls, first seen on the new Buick Park Avenue.One benefit was that the cruise control was integrated into the gearbox' electronic control module, improving the ability to maintain a set speed while avoiding needless shifting, thus lowering fuel consumption and noise levels.

The 4L80-E (and similar 4L85-E) is a series of automatic transmissions from General Motors. Designed for longitudinal engine configurations, the series included 4 forward gears. It was the 4-speed electronically commanded evolution of the 3-speed Turbo-Hydramatic 400 , first produced in October 1963.
