Easy install

I was looking for a little more power and MPG for my 1998 Chevy pickup to pull a camper trailer. Two trips out and it seems that I'm getting about +2 mpg and more power pulling up hills. Install was simple!

I can feel the difference in the shift pressure and torque of my truck alot. The shift points are wider and I was able to raise my top speed to a max of 125mph. Good buy, and great price.
