I was wondering if anyone uses automatic transmissions on road courses. I remeber there was a few autoxers that did several years ago. It's not that I don't want to go to a T5 or even T56, I'm just doing the bad thing I do & think too much about stuff! (IMG:http://www.frrax.com/rrforum/style_emoticons/default/dry.gif) (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rolleyes.gif) I even have a Hurst shifted T10 with everthing for the 74 camaro.

If you have access to some tuning software, you can change the shift points. (upshift, downshift, tc engage, tc disengage)
For example, I've got mine set so it won't automatically downshift from 3 to 2 if I'm going over 45 mph. And 3rd is good to 135mph too. Even with the shift points changed, you can still manually downshift if you want/need to. It's also currently upshifting from 1-2 and 2-3 at 4500 rpms, but that's just because of the turbo. The street tires are just starting to spin (vss shows a 5mph spike/bump that settles back down to a steady climb on the scanner chart) right when it upshifts. I can manually hold it down in a gear longer if I want to. Makes the car much more manageable this way. |
