when i floor it in my truck it takes awhile to get out of first gear and i want it faster out of the first two gears and better throttle response , any parts i can add to better this i already have a K&n cold air intake ,

1997 chevrolet crew cab c3500 5.7L longbed automatic

 

automatic trannies dont work like that.

 

throttle response off the line isn't so great when you have a heavy vehicle like you've got....invest in some lower gears, headers, and a tune

 

I hear you buddy, I'm replying to the post while I wait for my truck to accelerate from my flooring the pedal, oh, I think it's starting to speed up!

 

a quickshift kit will make it shift faster

 

I remeber the shift kits from years ago, but I thought the new computer transmissions could be reprogrammed. I do know the common wisdom is that the automatic transimission spends time in both gears while shifting to smooth out the shift. This causes more wear on the transmission than having a kit which essentially is a spacer that causes the shift to happen faster and be a bit more abrupt and cause a little jerk for the riders. This also is supposed to increase your mileage a bit because you don't have two gears fighting each other.
