Hello and welcome to JustAnswer!

There are many things that will cause a transmission to go into limp in and it will take some testing to determine what is going on. The trans goes into limp in when the trans controller sees a failure that will prevent proper operation and sets fault codes.

There are a handful of things that could be going on ranging from solenoids, speed sensors, wiring, internal trans issues and even the trans controller itself. The first step in diagnosing the problem will be to use a scan tool or code reader to see what fault codes are setting and testing can be done from there.
