Introduction
Thank you for purchasing BigStuff3’s GEN3 PRO SEFI Powertrain Control system with integral
Transmission Control! BigStuff3’s GEN3 ECU is the only aftermarket engine management system to
integrate transmission control into a single ECU! BigStuff3 is currently offering transmission control
for GM’s 4L60E/80E transmissions.
The first true GM electronic transmission was the 4L80E, introduced in 1991. The 4L60E followed
the 4L80E in 1993. Computer-controlled transmissions have changed automatics forever. Just as fuel
injection has made the engine more powerful, functional, and reliable, the electronic transmission
outperforms and outlasts any of its predecessors.
