I know tech has advanced a lot since 1992, but if my old Tempo was any indication your transmission will last a LOT longer behind a CNG powered engine because there's a lot less power available. I got very nearly the same MPG/MPGGE on CNG vs. gasoline in the Tempo, but horsepower was down by probably a third or half. It was still driveable barely in Phoenix, but wouldn't make it up any hills in a town with elevation changes - that was a 4cyl car in good mechanical shape.
