Hi all, I finally got my new tranny I went with the TKO-500, I also got new pullies and a C&L mass air kit Car runs very good. haven't gotten it to the track yet. My brother was reading car craft and they tested the TKO 500 with a 3.91 rear end gears and a 26" tire and they came up with 5.13's is that right? first gear with the tko is 3.27 and my rear end gears are 3.90, my D/R's are 26 inches. First is pretty steep now. any thoughts
