Yep, this manual does include the transmission pressure control valve replacement. It’s got the step-by-step procedure for the common gearboxes in that truck — 6L50/6L80/6L90, 4L60-E/4L65-E/4L70-E, and the Allison units.
You’ll find removal/install steps, torque specs, and the hydraulic schematics so you know exactly where that valve sits in the valve body. So if you’re tackling it yourself, the manual’s got the details you’ll need.
