more 904 trouble

I know how to install a coverter! And to say nothing is wrong with 904's ? The lock up version was terrible and so was the late 90's dakota and ram truck tranny's! I would much rather have a 727 I can use but the budget will not hold that right know. I didi take the trans apart that wa in the car originally this one was rebuilt. One day on my way to work and the car sort of jumped out of gear so I put it back into gear and thats when all the trouble started. I just took this trans apart today and I found slag from the casing between the clutch drums and the housing and a bunch of metal inside the valve body so im hoping I can clean this one up get it back together and on the road by the weekend.
