Retired Ford transmission development engineer. Good company to work for as I got involved in many interesting projects. We had McDonald Douglas engineers come to work at Ford when MD was cutting back. They were amazed at the miscellaneous, various and sundry sciences and technology which the engineering and build of an automatic transmission involve.

The work took me to Indianapolis, Fairfax, Batavia, Livonia, and Sharonville plants. Good people at all the plants who are very interested in delivering a very satisfying product at a reasonable cost. The most interesting project was the development of a pressure control system which involved an H.P VXIc Chassis with two embedded controllers, Alphi closed loop controllers, Atchley servo valves and Dynisco pressure transducers. We could control transmission oil pressure from 0 to 300 PSI at temps from -40 to 300 �F with rise times of 90 milliseconds and hit the target within 3PSI regardless of the change in compliance of the applied component. Digital data sampling and analysis is a science unto itself. Pressure control in a transmission is open loop and is accomplished with Varible Force Solenoid and Pulse Width Modulated valves. Shift scheduling is done with On / Off solenoid valves.

Also worked for Muskegon Piston Ring where Ford was the most demanding customer.

Now, speaking of Nitrogen in you tires, you wouldn't be interested in feul line magnets, swirl-a-gigs for your air intake, or some goo to put in your oil which will pop the seals off your valve stems the first time you start in cold weather would you? Sorry for the long post.
