I purchased a 2014 Dodge Durango approx. 1 year ago from a dealership. I previously owned a 2013 with no issues when it was totaled in a rollover accident. From the start the 2014 didn't seem to accelerate properly, there was alway a delay in when you pressed the gas until it responded but I was told it was probably because it had a larger engine and the 2014 had a transmission with more gears (8 as opposed to 5). Then it started not shifting properly in automatic. Between 1st and 2nd gear it would shift very hard and throw your head back and shifting out of 5th gear would do the same thing. Eventually it would not shift higher than 5th gear in automatic or manual... then it wouldn't shift out of 1st in automatic all together, but you could get it to 5th (sometimes in manual) but not often. I had the dealership look at it, a transmission shop and 2 auto repair shops. They all said it needed a new transmission and to flush the fluid in the transfer case. I put a new transmission in and did the flush and its still doing the same thing. It doesn't accelerate properly, shifts hard when going into 3rd gear or 5th gear. In addition to that it has flashed the error code "Service trans press brake when stopped key off engine to engage park" which it didn't do with the old trans and looking it up online seems to be related to the Dodge issue with the vehicles shifting out of park on their own. It hasn't shifted out (yet) on its own and stopped flashing that code but the transmission shifting issue still remains. Does anyone know what needs to be fixed on it? There are no error codes when hooked up to diagnostics. I don't want to have to replace the transmission again because I know its going to get to that point again if whatever else that is causing this issue isn't fixed.
