I'm installing a 700r4 Trans go shift kit from Dana at Pro built. There's a modification for wide open throttle 3-4 shift. Which you install 2 allen screws to the TV plunger sleeve. My question is what are the pros and cons to this modification as I'm not really understanding what it will do performance wise to the trans.

 

You still will have downshifts around town at speeds less than 55 - 60mph, but once you get above a certain point, the 4-3 downshift will get harder to make until at higher speeds it will not downshift "at all". If you want third gear, just grab the lever and bring it back to third and give it a little gas at the same time and you will have third instantly. You will be able to hold third to any rpm and move the lever to fourth and have it right now. This works great at higher speeds where you want to go around somebody, but do not want it to downshift when you just want WOT in fourth gear.

 

Thanks!

 

Who here has done this mod, and do you like it?

 

So has anyone tried this or what?
