How did I get 3.96 gears??
Since I got my new tranny put back in, I have been averaging about 11mpg. It was getting 19+ before the tranny build. I noticed 2 things tonight. First, it doesnt seem to be shifting into overdrive. It is turning 3000rpm @ 60mph in O/D and when i shift it into D the rpms dont change. Any ideas? Second, I have 225/60/R16 tires. And 3000rpm @ 60mph with those size tires in 3rd gear (1:1) yeilds a 3.96:1 final drive ratio. I thought a the 2.89 H-D diff swap into a 3.06 tranny yields a 3.29 final drive. My tranny guy had to swap different gears to get everything to work without a matching ring gear to thr 2.89 set. I wonder if this is what gave my the lower gear? Any ideas?
