your car just got the same problems my car,i did troubleshoot,it is ceu/cem problem and shift solenoid E electrical problem too. you need to change a new CEU/CEM MEAN Control electrical unit/ control electrical motherboard specailly it call computer box.and shift solenoid E electrical code is transmission problem.don`t buy CEM at dealership it is too expensive it cose about $320,but if you order online it about $199 or junkyard about $75 but it hard to find it because alot of people took it all.
