4L60E AND 4L80E AUTOMATIC TRANSMISSION CONTROLER

4L60E / 4L80E Transmission Control Modular Assembly
P/N 12497316 This Assembly includes the transmission control unit (TCU) P/N 12489489, wiring harness P/N 12489490, Specifications P/N 12489491 (13 pages, 8 1/2 x 11 in size with detailed information - not shown), TCU/Laptop interface cable P/N 12489579, and the TCU/Laptop Interface Software Diskette P/N 12490207. The control unit and programming software is designed to work with either a 4L60E or 4L80E transmission. The TCU/Laptop Specifications provides you with a step-by-step guide to a PC based control system for our Transmission Control System. This software allows you, through your PC, to take precise control of the transmission functions. You can control and alter the feel of a gearshift, the timing of the gearshift, and the application of the lockup in the torque converter. T-Com also allows you to have the transmission shift at wide open throttle (WOT) solely as a function of engine RPM, while it continues to follow a shift curve based on road speed and throttle position during part throttle driving. T-Com is designed to allow maximum tuning for the performance enthusiast. the system comes already loaded with a transmission calibration that works quite well in most performance applications. There are only four fields in the Global Calibration that “MUST” be entered for the system to function with the pre-programmed calibration. In order to get the system up and running, you simply have to enter the tire size, rear axle ratio, number of engine cylinders, and if you are using the 4L60E or 4L80E transmission. The TCU comes with a generic calibration file installed. However, since different users can have wide ranging expectations of how hard and when they want the transmission to shift, the edit features allow for “customizing” the characteristics to meet those expectations.

Note form the Webmaster: Most published system requirements for any software like above will usually only be enough to just be able to allow the program to function, if that. Most people won’t have a computer as far out of date as what they are stating above, so there shouldn't be any problems running the program for them. Some knowledge of MS/DOS will be helpful to you too.
