I tore my tranny out and apart and confirmed my suspicions. There is no second gear in my tranny only the 36T first gear. Doing the math and shooting for Novak's suggested 22:1 reduction for monster trucks I would need a spur/pinion reduction of 3.0067:1. My current gearing of 64/22 puts me at 2.909:1 so I am slightly over geared right now. I'm going to gear it down slightly for safety and keep my current tranny gearing. Only cause I have gears to get me where I want without spending any more $

Stock revo diffs = 2.643:1 37/14
Tranny
input-idler = 1.538:1 20/13
idler-1st = 1.8:1 36/20
*idler-2nd = 1.55:1 31/20

Going to go back to 64/18 (3.555:1) for now, ought to keep me plenty safe!
