    Thank you very much. I have a 4L60E that I'm about to put an LQ4 into with a cam. I'm going to buy a 4L80 as soon as I get a deal.

    I'm sick of 4L6X replacements. I'm sure everyone else here in the forum feel the same. Ant that's with stock engines! The LQ4 in that Denlai is stock and has outlived multiple 4L65Es. Time for it to move to a cleaner truck with more power.

    Just so you know that is not a stock OS. If you want here is a stock one.
