GM 4T45-E Transmission
The 4T40-E and 4T45-E are a series of automatic transaxles from General Motors. Designed for transverse engine configurations, the series includes 4 forward gears. The 4Txx family replaced the Turbo-Hydramatic 125 transverse three speed automatic introduced in 1980. The "-E" series is electronically controlled and features an automatic overdrive transaxle with an electronically controlled torque converter clutch. Since non-electronic versions of these transmissions do not exist, it is conventional to refer to these models as simply 4T40 and 4T45, leaving out the "-E". The 4T40 and 4T45 were assembled at Windsor Transmission in Windsor, Ontario, Canada. 4T40 The "MN4" 4T40E is able to handle vehicles up to 4000 lb (1814 kg) GVWR. The final drive ratio can vary depending on the car's curb weight and engine power output. 3.91, 3.63, 3.29, 3.05, 3.69, and 3.42 are all of the available ratios used in the 4T40 (and 4T45) transmission; Made possible by using combinations se ...

List Of GM Bellhousing Patterns
The following is a list of GM bellhousing patterns. Though General Motors has manufactured many different engines, it has kept variance in the bell housing patterns to a relative minimum. Chevrolet V8 pattern This was so named because it began with Chevrolet's V8 engines. * Chevrolet big-block V8s * Chevrolet small-block V8s * GM Vortec 4300 90° V6 * GM Iron Duke RWD inline 4 (early RWD Variants, later versions may use a FWD pattern, and have two possible starter locations) * Jeep with GM Iron Duke inline 4 2.5L/151 in³ (1980-1983). These use a Chrysler custom Torqueflite 904 automatic transmission with an integral Chevrolet bellhousing. Do not confuse with later AMC 2.5 L engine that uses GM small corporate pattern ( see below). * Chevrolet Turbo-Thrift engine (post-1962) * Chevrolet 153 Inline 4 (Chevy II, pre- Iron-Duke - includes the Vortec 3000/181 industrial/marine crate motor) * Detroit Diesel V8 6.2L and 6.5L * Duramax V8 * Generation III V8s with modificati ...

Hybrid Vehicle
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. The basic principle with hybrid vehicles is that the different motors work better at different speeds; the electric motor is more efficient at producing torque, or turning power, and the combustion engine is better for maintaining high speed than a typical electric motor. Switching from one to the other at the proper time while speeding up yields a win-win in terms of energy efficiency, such that it translates into greater fuel efficiency. Vehicle types Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle. * In a parall ...
