Shifting points of camaro 2010

[odd boy]

Hi to the best supportive guys in the best forum.....:grin:

I am tuning Camaro 2010 auto (L99) engine. I have a problem with shifting points. The problem is that: the set point is 6300 rpm but it shifts up at 5500 rpm from 1st to 2nd. For the rest of the gears it runs great. (All of the above scenarios happen when the selector is on D position)

Another issue, If the pedal is pressed fully while the car is moving at speed of 40 (KMH) and the selector is on (D) position it does not go to gear 1 it goes back to 3rd.

Your help is appreciated in advance

would you elaborate

Trans runs a mix of rpm and speed for shifts. The first qualifier was previously speed. Maybe that has changed in 10's. Maybe not/ How would I relate rpm to speed to check this without knowing diff ratio from tune & tyre size?
