The 4L60E (and similar 4L65E) is a series of automatic transmissions from General Motors. Designed for longitudinal engine configurations, the series includes 4 forward gears and 1 reverse gear. The 4L60E is the electronically commanded evolution of the Turbo-Hydramatic 700R4 , originally produced in 1982.
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 4L60E is not easily swapped with the 4L60, as the 4L60E depends on a powertrain control module (PCM) to shift. [2] The 4L60E went into service in trucks, vans, and SUVs in 1993 and in all RWD passenger cars (Corvette, F and B/D bodies) in 1994. In 2001, an updated version — the 4L65-E, was introduced.
A park by wire system engages the parking pawl of a transmission using electrical means, without the traditional mechanical system which involves linkages between the gear shifter and the transmission. Park-by-wire can be considered a part of a shift by wire system, as it shifts the transmission into park mode. [1]
The 5L40-E was designated in either "M82" (rear-wheel drive) or "MX5" (all-wheel drive) versions for service in BMW vehicles from 1999 model year until the design was superseded by (for BMW) the 6L45E and (for all others) the 6L50E series electronic automatic transmissions in 2007 .
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 4L80-E uses two shift solenoids, initially called Shift Solenoid A and Shift Solenoid B; they were later changed to comply with OBD-II regulations to 1-2 shift solenoid and 2-3 shift solenoid. By activating and deactivating the solenoids in a predetermined pattern by the PCM, four distinct gear ratios can be achieved.
The 6L 50 (and similar 6L 45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors.It is very similar in design to the larger GM 6L 80 and 6L 90, and is produced at GM Powertrain plants in Toledo, Ohio; Silao, Guanajuato, Mexico; and by the independent Punch Powerglide company in Strasbourg, France.
