Supermatic 4L85-E
Supermatic 4L85-E From GM Performance parts. Anyone out there running one of these? And how about the GM controller?
They say it can handle the "mighty ZZ572/720" crate engine.
It comes with a production torque converter (approximately 1,800 - 2,000 rpm stall speed). Price is around $4000 with converter and GM controller.
