I jumped started it with a 24 volt and then I had to put a new dash in it and now it does not shift out of 2nd in to 3rd and befor that I had the transmission flushed . What can I do now I'm not a transmission person. Help me pleaae

 

If that problem started when you jump started it then the problem most likely isn't in the transmission. My bet would be on the vehicle computer being toast.
