4T40E,4T45E

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 the non-electronic versions of these transmissions does not exist, it is conventional to refer to these models as simply 4T40 and 4T45, leaving out the "-E".
