What I watched was a perfect example of trying to crawl with an automatic and not enough gearing. Lets see, a C6, 205 (maybe a converted 203?) either way only 2: low range. And judging from how it acted 4.10 or 4.56 gears. Every obstical it encountered stopped it, then took a blip of the gas to work the converter to get over it. For what they were trying to do they really should have had a doubler in there, it would be just as fast but so much smoother going over stuff. And it would be doing it without jumping the front axle into the air.
Thatnk's for showing us how not to do it.
