GM 4L60E Level 1.5 Full Rebuild Part Five: Valve Body Assembly and Shift Calibration

I continue the rebuild with valve body assembly, showing you step by step reinstallation of every valve, plug and solenoid into the valve body. I then vacuum test it, move to spacer plate repair and orifice sizing, come back to the valve body to make one final change. From there, I put the 1-2 accumulator housing and prep those components for final installation onto the case.
