I forgot about this thread.
There have been LOTS of changes as of late:
--Mark Bowler has emerged as a master of electronic transmissions. His units are pricey, but so is an 800HP TT engine.
--Mark Bowler has also developed electronics that will allow you to seamlessly perform gear changes AND gear splits by way of my paddle shifter. So if you put a Gear Venders unit behind a 4L60E or 4L80E, you get a 6/8 speed manumatic. (Six speed with the selector in 3rd gear, eight speed with the selector in OD)
--We are working with Pro Torque to develop small diameter (light weight), high efficiency, multi disc lock up torque converters specifically for pro-touring automatics. We will put one in my car this week for final testing. We will follow up by putting one in the red car. Then I can explain in greater detail. We expect to start selling them in 60 days.
More from Bowler Transmissions:
--They offer valve bodies modified for engine braking. These are for 4L60E class transmissions. also available for the 4L60E is a revised solenoid schematic that turns it into a six speed. You can see and hear the modification in action.
