Auto trans, which did you use?

The 545rfe is easier to put into the car than a NAG1 is going to be. The 545 just needs a truck PCM to control the shift patterns. Bonus is it also controls the 5.7/6.1 engine.

The best part is the 545's can be had for less than $500 in some cases. I've been selling one for about a month for $400. So they are out there.
