Our transmission went bad on 1999 Honda Passport V6 2WD. It was justing jumping gears then went to nothing. Put a new one in & still does nothing. Any answers on why?

What is your question?

Always starts up fine. When old transmision went it was jumping gears then it wouldn't move at all. We just installed a new transmission & will not move at all still. Would like any help on what could be causing this. Thank all you dearly in advance.

How long has your 1999 Honda Passport had this problem?
