The TorqueFlite transmission has been around since mid-to-late 1950s. There have been many changes surrounding the manual shaft and rooster comb through the years. This transmission shaft controls the position of the manual valve that directs oil for the gear ranges, but it also is used for a Reverse light control as well as Park/Neutral

In fact, looking through the past 10 years of OE bulletins, I find that the ratio of actual repairs versus computer reprogramming has changed dramatically, totally favoring computer reprogramming.
