GM Performance Parts’ all-new SuperMatic Transmission Controller
system is the most fully integrated and user-friendly transmission
control package in the aftermarket. It is designed for hot rods and
other vehicles equipped with LS engines and GM Hydra-Matic
4L60- or 4L80-series electronically controlled transmissions –
including GMPP’s high-performance SuperMatic transmissions.

The revolutionary system makes installation a simple matter
of completing a few fully terminated connections that link the
transmission controller to the engine controller. It comes preprogrammed
and is ready to drive, once all the connections are
made. No additional set-up programming is required. That enables
the installer to get the vehicle running quicker.

Two versions of the SuperMatic Transmission Controller system
are offered:
• p/N 19257634 works with 4L60-E, 4L65-E and GMPP’s new
SuperMatic 4L70-E
• p/N 19257661 works with 4L80-E, 4L85-E and GMPP’s
SuperMatic 4L85-E transmissions

The controller system is designed to operate with GM Performance
Parts’ E67-based engine controller, which operates all of GMPP’s
LS-based crate engines with electronic fuel injection. And while the
system is designed for “tuning-free” operation right out of the box,
it also includes optional connections that allow adjusting a number
of calibration settings, including shift timing and shift fi rmness.
Also, the system can be confi gured to operate the transmission in a
manual mode, to enhance the performance driving experience; and
it supports most types of tap shifters or wheel-mounted paddleshift
systems. Comprehensive adjustment instructions are included
with the kit.

If all those features weren’t enough, the system also includes onboard
data logging capability, which allows the operator to capture a
data trace, which helps maximize performance.
