4L60E High Performance PT4 - Valve Body and Spacer Plate Mods

In PT4, I walk through some basic mods that you can do to the valve body and case to achieve gains in shift quality and overall performance, in lieu of installing a shift kit. I also discuss calibrating your shift firmness via the spacer plate as well as other transmission components to ensure your transmission shifts the way you want it to in a high performance application. If you know of a valve body mod, tip or trick that I didn't cover, please post it in the comments section. If/when there's enough input, I will do a "PT 5" and recognize your contributions in the video!
