Does anybody have any information on these yet? I saw an advertisement on it in the latest Chevy High Performance Magazine on page 55. I went to their website and couldn't find anything. It looks like it's based off of a 4L80E. It lists the gear ratios 2.97, 2.23, 1.57, 1.18, 1.00, 0.75

I wish they would have went with a deeper 1st gear ratio or a higher overdrive.

Does anybody have any idea on how much this thing is going to run?

There is nothing wrong with those ratios...

Anytime you go past 0.75 in a final drive... the efficiency plummets. I think they chose great ratios for what this transmission is designed for.

Drop a set of 3.25-3.50ish ratio gears into the differential and you'll get the best of both worlds.

Bowler in combination with Twistmachine can help you with similar options, offer great customer support and sponsor this site and PT. I speak from personal experience with regards to Twistmachine.

When you do a little search on this forum and/or the PT forum you will find more info with regards to these products.
