Has anybody else have problems with the shift lever on 2016/2500 It has did it a couple of times in the 16 months I have owned it. But I thought it was me not doing something, but in the last two days it is becoming a recurring problem. I did find if I shift the lever by pulling on the shaft half way down it works easy. Of course it has to act up on the week end and the dealers is 20 miles away. Anybody have any ideads or suggestions as to what can be the problem?
