[QUOTE="RedRocketMike, post: 16653052, member: 51242"] Definitely does. That's mostly why I like the 8.1 Silverado over the 6.0. The 4L80 has a ridiculously long first gear. The Allison 1000 in the 8.1 trucks has a much more aggressive first. Although, if you dig around old forum posts there is talk about the 8.1s in the Suburbans/Yukons having a less aggressive tune than the trucks, in addition to the gearing disadvantage. [/QUOTE]
