My '06 3500 was having issues shifting from 1st to 2nd (taking it's own sweet time) I changed the Gov sol and transducer and now it will not go to 1st but starts off in 2nd and hit the other gears just fine. I think it already had the bigger solenoid, but the replacement was stock. I use this truck to pull building kits and need it in top order...help, lol
