I noticed from the archives some of you were wondering how this thing was installed, I couldn't resist buying it, I only had my truck for a month and was frustrated with the way it was shifting

and jumping in and out of OD. Now. I gotta say, this thing may be over priced for what is inside of it, I don't know? and now I don't care. Some gadgets are just that. "gadgets" this thing has made me enjoy my truck. I'm not going to try to sell this product, I just wanted to follow up on the discussion. the "Happi Box" Made me happy.

I have one in my 99 and it made a big difference and allowed me to break 14 seconds in the 1/4 mile with my old mods. With 450-650 hp it does not matter who made your TC and how many plates it has if it locks and unlock 100's of times a second.
