Hello everyone. I've been breaking my head on this issue for about a week now, hopefully someone can help. I have a 2014 freightliner cascadia DD13. I'm getting several codes but mainly SPN 5606 FMI 19. My truck starts and accelerates fine on neutral, once in gear it only goes on and off up to 3 to 5 mph. Reverse works fine. Thanks for your help in advance.

IIRC-that relates to connection issue-and more than likely because of year it's a harness issue.
If it was taking forever to shift from neutral to drive but would be slow shifting to reverse that
is actuator and internal-a common issue on early models--And I'm guessing this truck has a
DD12 transmission or is it a Eaton Auto Shift?

Can't help with that one, better off to call a local dealer to get info.
