Ihave code p0731 stuck in 1st ratio .. what mean that code?

obviously refers to auto trans , could just need the trans fluid level topping up or even changing , if this does'nt resolve the problem then a more in depth diagnosis would be required at a repair shop as could be the ECU for example but do the fluid checks and go from ther ,keep me posted

It means that the transmission is not seeing the right values between the input and output speed sensors. Is the transmission stuck in second gear? Does the speedometer work?

    P0732 Gear 2 Incorrect ratio

    It seems like you were having an issue with your transmission but if you cleared your light and it has stayed off I would just keep a close eye on it.

    Hi, the premium system was just revamped and currently is having a little problem of not letting me post a solution to your premium question but I figured I would post the answer here for now until the problem is resolved. Sorry for the inconvenience and the time it has taken.

    P0732 Incorrect 2nd Gear Ratio
    P0734 Incorrect 4th Gear Ratio
    P0736 Reverse incorrect gear ratio

    The codes you have are all gear ratio error codes fordifferent gears. The most likely cause to see all of these codes together wouldbe an input or output speed sensor. If your speedometer does not work, replacethe output. If it does work, I would recommend an input speed sensor. Thiscosts about $25 and is easy to replace. The speed sensors are on the left side of the transmission. You willneed a 1" socket to replace them. Let me know if you have any furtherquestions with this van. We have actually owned a few of these, so prettyknowledgeable with them.
