904 Transmission Stopped Going Into Gear

Yup, a lil while now. I rebuilt my first trans in a 73 Dart back in 1980. I'll be 70 next year. My very best advice to you at this point is "Don't order anything until you've made a list of all the parts you need." If your direct drum is bad and the pump cover is bad, plus the converter is bad...that's beginning to add up to more than another trans would cost. Even most bad 904s have a better converter than yours. Post pics of the inside of the direct drum and the back of the pump where it rides. Also, if you have any destroyed thrust washers, check those surfaces involved for scoring. ..I don't see how you could be very adept at replacing bushings yet at the same time not be able to identify a bad one.. From the pics you've posted, I can see that too little attention is being paid to critical areas. I'm advising on this build because I like to see folks rebuild their own transmission; especially a 904 and a lot of viewers might be interested for their own build. But in all honesty, I don't have high hopes for this build if you're going to cherry pick my advice; because everything I suggest is tried and true over a span of almost forty years. Like my 8th grade nun teacher used to say, "A word to the wise is sufficient".
