i bought an 07 qc 4x4 with the 5.9. with the superchip programmer in performance, it is 460 hp and 890 lbs of torque. is my trans strong enuf for these numbers? i wont pull my trailer in this setting. the power is sure fun and i'm getting between 22 and 23 mpg on the freeway!!!

 

Is it manual or auto?
