I have just swapped my old engine out for a newer used and it is running swell. The only problem is that I took it for a test drive. I reversed out of the drive way. Started down the street but for some reason it switch over into 2nd gear. then it shut down. I stopped turned it back over but it will not go back into gear at all. Any Ideas wht might be wrong??
