Sometimes will not start until I jiggle the shift (in park). Why? on 2005 Dodge Sprinter 2500

There is a sporadic electronic or other connection problem that prevents engine start. Have had repeated bouts with the transmission failing to upshift and two Freightliner dealers' less than satisfactory but costly service. Not sure if this is related.

Get your shifter linkage adjusted. It attaches to the neutral safety switch, not supposed to start unless it is registering park (or neutral) to close the switch so the starter can engage.
Thanks for your prompt response.
agree with professor also could be shifter bushings
