Couldn't agree to this more. The game calls it FULLY CUSTOMISABLE transmission for a reason!
I'm also with JeffKill - multiple setups should have been a given.
My support is given... It's a huge let down. It takes away the advantage for the guy who has taken the time to learn how to adjust the transmission by giving everyone the same option. And yes, of course I know how to setup a tranny... Been doing it since GT1
I seriously hope that this comes in the next update because i believe the individual ratios can make a massive difference in acceleration when done properly and I would love to surprise people online with much higher powered cars.
