The 4L80-E (and similar 4L85-E) was a series of heavy-duty automatic transmissions from General Motors designed for longitudinal engine configurations. The 4L80-E was heavily based on the Turbo-Hydramatic 400 first produced in October 1963, adding electronic controls and an overdriven fourth gear. 4L80-Es were optioned only in Chevrolet/GMC pickups, Suburban 2500s, vans, and commercial vehicles, and the Hummer H1. It was also adopted by Rolls-Royce in 1991 and modified after extensive testing,^[1] and used initially in the Bentley Continental R, and subsequently other Rolls-Royce and Bentley vehicles. The 4L80E and 4L85E were built at Willow Run Transmission in Ypsilanti, Michigan.

Gear ratios:

4L80-E[edit]

The 4L80-E (RPO MT1) is rated to handle engines with up to 440 ft·lbf (597 N·m) of torque.^[2] The 4L80-E is rated to max GVWR of 18,000 (Axle and vehicle dependent)^[3]

The 4L80-E uses 2 shift solenoids, initially called Shift Solenoid A & Shift Solenoid B, later changed to comply with OBD II (On Board Diagnostics revision 2) regulations to 1-2 Shift Solenoid & 2-3 Shift solenoid. By activating and deactivating the solenoids in a predetermined pattern by the PCM, 4 distinct gear ratios can be achieved. The shift solenoid pattern, also sometimes referred to as solenoid firing order, is as follows;

Shift Solenoid Pattern[edit]

No power results in 2nd Gear as 'Limp home mode'.
