We've test fitted, measured, scratched our heads, tested again, looked at the calendar, scratched our heads again... and we've determined that the 6L80E, while cool, is not going to fit this car in the timeframe required. The trans is just too big, and the amount of surgery needed is going to take a long time, and then it would take just as long to un-do if the trans didn't live up to expectations.
So we talked to Mark Bowler at Bowler Performance Transmissions about his upcoming project... a collaboration with Bowler, Twist Machine, and Gear Vendors to create an 8-speed 4L65E auto that can be paddle-shifted (is Shrifted a word?) up and down through 8 gears. Sounds cool to us, and it actually fits in the car! So the story changes a little, but moves 2 gears ahead!
