None of the cars in the above posts are computer controlled. The small exception would be the delayed upshifts that occur on the 93 and the 90 129 chassis. Delayed upshifts are achieved by the engine management controller (during cold running) electrically switching a vacuum switchover valve which then transmits vacuum to the actuator on the control pressure cable. This changes the affect that throttle movement imparts on the control pressure valve in the trans. I'm not sure if it will cause a start off in first gear but it will quicken the point of downshift.
All of these trannies use standard hydraulic valve body logic. Nothing is learned!
