ok so i found this part online. from what i read it will let you stay in fourth gear upto 90% throttle. what do you all think?

"700R4 full throttle 3-4 up-shift sleeve. Now you can have a full throttle 3-4 shift. At 80 MPH it takes 90% throttle to make a 4-3 downshift. Can be installed without removing the valve body. The Up-shift Sleeve also eliminates part throttle 4-3 downshift for less gear searching. This is an extra option on the 700 Raptor. Not recommended for motors over 250 horse power. Cost $49.00"

 

How often do you really need to accelerate at WOT in 4th?

 

drag racing, right now i can only go up to 3rd because if i try fourth it will just go to 3rd

 

You want to be running through the traps at your redline in 3rd. If you're running faster than that, you should get some numerically lower gears for your differential.

 

4th gear is a .75 gear you wnat to be in 3rd (1:1)at your peak rpm going through the traps. if you need fourth you need to step down your gearing.

 

i have 3.23's right now and im spinning my motor pretty good, i am about to go to 3.73's do you think that will help enough?

 

i think you should try 3.42's. the 3.73's will probably suck because you will end up in 4th way before the traps. some ppl like it but if you also like to drive highway, id go with the 3.42's.

 

You have 3.23 gears now? What rpm are you going through the traps in?
