Hi friend, this code don't have so many information, but there are some things that you can do. I'm going to give to you some tips to begin the diagnose. I hope they'll be useful. First try to pass all the gear shifts with help of a scanner that can view the activation signal of each gear (view and send activation signal), check the activation of the gears. So you have to pay attention if in first place the activation signal is present, then if the electro valves are activated according to the signal sended by the scanner.
If the signal is present but there are not activation of the valves, you could have problems with the conectors or lines, or some problem with the valves, if all look good and works good with the scanner test, so the problem is out from gearbox and his control module.
