904 low gear set

IDK, but I think the stall will be a big player
There is only 11% difference from 2.45 to 2.74. What's that come to in ftlbs at stall?
But it's a bigger jump from 2.74 to 1.45; 53% split, versus 59% with the standard 2.45 low. That is mathematically 400rpm at a 6600 rpm shift, but wouldn't make a big difference with a 4000+ TC.
