I wish I bought it sooner

I had been eyeing this thing since j bought my truck 2 years ago and finally pulled the trigger. It completely fixed my trucks issue with the torque converter hard shifting or stuttering during hilly conditions where v4 mode would activate. The truck drives and shifts much smoother now during those situations. For daily city driving i notice no hit on the mpg either. However for highway there is a slight hit, maybe about .5 to 1 mpg.
