2011 3500 dually with 240k on the odo. Just deleted with a smarty ME tune (for racing of course) just a simple set up. Hopped on it today to show the pops powerstroke what’s up and it didn’t wanna come out of first. It went into 2nd when I let off but it kinda made ny heart jump up to my throat real quick because I had plenty of trans problems in my 03 cummins and then had an 02 6 speed so I’m a little insecure getting back into another auto. Anyone know what’s up! Did research and couldn’t find the same situation maybe I’m not looking hard enough.
