I have a 2012 F-250 ccsb lariat and the shift from 3 to 4 seems to be a bit prolonged as if the converter is slipping and wont go ahead and push it into 4 gear. Also it will want to downshift from 3 to 1 and feels like the car behind nailed you. I have read that the early 2011 had some of this problem and the dealer reflashed the tcm and it did not do much good but as mine being a 2012 mine should have been flashed with the lastest tcm flash from the get go?? The *** and egr fell off and am running Kory Willis tunes through ez lynk so the stealership is probably out of the question.the truck has been D****** for 1k so maybe this has something to do with it? I have also read that changing a couple solenoids( dont remember which ones) will fix the problem, but need a little more help. Any info would be greatly appreciated!
