904 Transmission Stopped Going Into Gear

The only reason yours looks like the other one is because you have no button thrust washer. See, here's the question: Why would you need a thinner thrust washer now, but before that thrust washer was just fine? Stick a pry bar in the tailshaft snap ring access hole and try to push the bearing rearward. Note: Measure the thickness of the two front (larger) thrust washers and make sure they are within specs. I think the problem is in the back train; not the front. Once that is resolved, you will probably have an excessive amount of front endplay. Are all your thrust washers original? I still think the problem is in the back bearing.
