So Now that I am going to have issues with the 904 should I keep it or buy the th400 thats attached to the 401 Im buying? Its a 4x4 th400 so I dont know what I'll have to do to get it turned into a 2wd but its cheap and works pretty good. I dont know what the condition of the 904 is in my gremlin, I was told "It shifted fine when I drove it" I can get a 727 if need be I just dont wanna pay through the nose to rebuild it since I swiped all my money for the gremmy. Thoughts?
