My name is Steve Powell, I have 41 years design experience with Ford and GM in Automotive transmission park lock system. Was lead concept designer for advance engineering, a blank sheet of paper design to production. An expert on the mechanical park, hydraulic manual valve, and electrical mode switch relating to transmission park lock manual shaft pivot point, includes park system vector analysis and the balance of forces. Worked on joint ventures with GM and BMW 6 speed, GM and Ford Motor FWD 6 speed and new 10 speed, GM and Aisin 8 speed pertaining to park lock. Also developed park stack-up procedures for park system that includes mechanical park, hydraulic overlaps and electrically to assure an arithmetical math clean safe design, no statistical allowed. Have extreme complete understanding of geometric tolerance, (GD&T) layouts to production release detailed drawings. Have a good understanding of shifter and shifter cable to transmission manual shaft pivot point. Have worked with GM Legal on several lawsuits pertaining to park lock.
