I have an 08 chevy 4x4, with a 2600 stall converter in my 4l60e. I tow a small rv. My uestion is the any way to lock the converter at lower rpms when towing. My truck has the power in overdrive to pull my trailer but the tranny temp starts rising real fast. Ive been pulling in 3rd, but with 4.56 gears that equals about 3000 rpm. Burns gas real quick! Gas is cheaper than a new tranny!

 

it can be adjusted to lock at any speed with tuning software.
