Inspection of a 904 torqueflite
On the forward drum and direct drum. I’m pretty sure it’s good. The only problems I have found so far are the reverse drum that has all the wear around the band surface area.
Are you talking about the direct drum being a bigger diameter....the number 1 behind the pump?
The direct drum and forward drum look right. I’ll compare them with pictures of the different measurements on them.....length, width and race diameters......as well as stack clearances and thrust measurements. One of these drums might not be long enough. Having the 904 here disassembled helps a lot because it’s just a little worn out and had nothing wrong with it.
the 1/4” movement. When the transmission is standing up on its bell housing. I can move the reverse drum up 1/4” off the bottom of the sun shell.....this picture is the reverse drum and band. I can move that drum up so that line meets the band. So far that’s the only thing strange I see and it might be normal to do that.

All the washers are present. It has a fiber washer on the pump and the one on the clutch hub. They haven’t been measured yet. I think this transmission is gonna need more measuring than the last.
I would have have done it last night for peace of mind..... but after driving 2 hours and taking that thing out in the hot sun....I was done.
The 999.....someone was in there and there’s no telling what they did. They messed something up I’m sure and that’s why there is metal in the filter like that. I think what they messed up is from the reverse drum back.....or maybe replaced 999 stuff with 904 stuff that looks right but isn’t. This is the mixing and matching Cuda is talking about.....they might have done that. I don’t think so but I won’t assume in this case.
