Auto - 3.6 w/ 3.21s vs 3.8 w/ 4.10
Beyond the obvious of it not being anywhere near the ideal gear set, would 3.21s w/ a 3.6 and 35s be worse, better, or the same as my 4.10s w/ 3.8 and 34s.
On the chart, they both fall at the bottom but I ran my 34s in my 07 for 90k miles with no complaints.

according to the chart, there doesnt seem to be much of a difference. ive been running 3.21 gears and 35's for roughly 10k miles since i moved back here to Pittsburgh. the 3.21's arent all that bad, but nowhere great either. i get roughly 15-16 mpg on highway but despite all the negative comments on the forum from other members i didnt really think they were all that bad but i just ordered yukon 4.56 gears to install in the next week or so.
