ask the governor that question.
FORGET the governor , unless the governor in the trans has failed. "SMOG" test ---what comes out of the tailpipe. JUST for an extreme example . trans has a failure causing it to start out in second gear but works fine otherwise , (I'M jus' sayin') that extra load created by starting out in second is affecting the tailpipe pollutants.If the torque converter lock-up clutch isn't working properly or it doesn't go into overdrive.....get it? all trans problems not engine ..yet they affect the tailpipe (in the end) (get it?)
