I bought my 07 this past June and gotta say, I love everything about my truck except the transmission. It made a cross-country haul with all of my household goods on it and the trailer. Great mileage, great power, never stalled or lagged.
My problem though is this, When the tranny is cold, it likes seems to have intermittent issues shifting back to first at a stop and likes to jump a bit and, if I don't take it really easy on the throttle from a start, it goes into some mode where it won't shift at all until 2500+ RPM until I shut the truck down for a few minutes to let it reset. This happens hot or cold.
All fluids were changed when I bought it and it has 220k on the odometer. Is this something that I can remedy with a MODIS or am i looking at a R&R? I'm new to Dodge equipment and unfamiliar with its eccentricities.
Thanks!

 

You have access to a Modis?

Scan for codes. Get it to act up and see if it throws any. For giggles, go into the trans live data and record all of the CVI numbers and post them up.
