Need a tune for my 14 Jeep SRT Transmission (looking 4 the trackhawk tune to compare)

Hello! I tuned my engine, it's running great... horsepower is a little bit over 500awhp but the limiting factor now is the transmission, I don't want to mess up my tranny, I need it to shift 500rpm upper than original 6800~6900 because my dyno graph is still going up when the transmission shifts...

BUT I don't want just to rise the shifting points without giving it more pressure or tweaking the shifting times...

So I need a reputable tuner to tune my transmission or a trackhawk stock file to compare the pressures and see if I can use some TH data over my trans tune...

I'd like to tune it all myself but the transmission is something I've never tuned in my life, a lot turbo and supercharged engines but never a tranny...

Hope someone could help... thanks!!!
