GM THM 4L80E ATRA MANUAL Repair Rebuild Book Transmission Guide 4L80-E

The General Motors 4L80E, in production since 1991, has become the workhorse of GM’s light truck series. This unit has also surfaced in some rather exotic and unexpected vehicles simply because those manufacturers wanted one of the best, most reliable units available at the time. Based on the bulletproof THM 400, which could take just about anything a car or truck could dish out without breaking a sweat, the 4L80E was the natural evolution of the 400, updating the design with a beefy overdrive section built
into the case in front of the venerable tried-and-true three speed. No longer does the old  overnor/modulator debate tell the transmission what to do, when and how much to do it.

Fully computerized control of the shift points, torque converter clutch engagement and line pressure control ensure that the 4L80E will be with us for quite some time to come, easily interfacing with the newest powertrain control and diagnostic computer systems.
