Hey guys really need some help here, just got a 08 dodge ram 2500 cummins 6.7 it has a built suncoast trans in it and it will shift good 1-4 sometimes waiting until 1800 rpms to get out of first gear but once u get to 50+ the truck will go into overdrive if its not warmed up yet but it will rev up then down for about 30seconds constantly until it decides it's done with overdrive then it will just stay in 4th gear and u can do 70 at 2600 rpms something not right and I don't have a warantee so I really need some help no check engine light or codes are on
