i just got a new tranny A4 and i am trying to get the car to shift at 6400 rpm. i keep bumping the limiter on 1-2 shift and 2-3 shift. does anyone have a formula or have a table i can follow to enter the right mph for 6400 rpm shifts. i cant use my TNT until i get this shifting problem solved. if it helps to know, my car has 3.73 gears, 3200 stall,26x10.5x16 e.t. streets. thank you.

1st gear 1MPH = 129 RPM and 2nd gear 1MPH = 69RPM

or you can just set say the MPH low and use the RPMs to get her shifting where you want or VICE VERSA... both have to be meet for the car to shift and also keep in mine A4's lag on there shifts

I think what 98TA is saying is try this:

desired shift 6400 rpm minus 50 for lag = 6350
6350 divided by 129 = 48.8mph.
1st gear set to 49mph and 6350 rpm

6350 divided by 69 = 92.0mph.
2nd gear set to 92mph and 6350rpm

I think I used 100 for my lag, but my points are very close to the above. I also have 6600 rev limit which I do not hit. Keep in mind, I did this on Predator not edit.

If you are using TNT you may want 150 to 200 lag, maybe more with TC. You'll have to try it out.

What would the factors be for 3.23's?

I have been hitting the rev limiter on the 1-2 and 2-3 shifts, so I finally broke down and bought the Predator. Should be getting it sometime next week.

TIA!
