Inspection of a 904 torqueflite

The finger nail catch. It is at the end of the machined path on the 999.

But On the 904. That machined path sits higher on the right side than it does on the left.

The reverse drum play.....my 904 has it as well. I’m going to put together both of them and look closer into why the reverse drum slides 1/4” or a little less.....off of the sun gear. Or it’s the reverse drum sliding off the rear planet. Not sure which.

How can I test a failed converter before installing it? Can I use air to manually activate the clutch and test for resistance in the stator and rotating assemblies?

I have seen that much before on the magnet when changing fluid. You right. It doesn’t take much to get them to look like that.

The metal on the filter was my major concern. That could be from the snap ring like you said....they dig out and leave metal in the system.

I can inspect every part......but not the converter. It’s dated on the front and stamped on the back 5/2014....doesn’t mean it didn’t fail.

I’ve never rebuilt one of these....but I have changed fluid and have seen particles and metal in the pan before. Of course.....there are the teeth on the Simpson set......but wouldn’t they present powder metal like on the magnet as opposed to bigger chips like in the filter.

I want to say when I changed the fluid in the 904.....I found stuff like that as well. Same situation but the fluid wasn’t as dirty.

But in saying that. If this was redone 5 years ago. The fluid should not look like that....at least I don’t think so..
Not unless some wear is going on that’s in natural. You would know about that more than I would.

Ill put the output shaft support and the output shaft itself from the 904 in this one.

Those bands are both black. I’ll replace them as well
