Inspection of a 904 torqueflite

Well.......this is the A999 transmission with a lock up clutch.
It has the lower gears, 5 friction direct clutch drum, 4 friction forward drum. We will have to see what shape the Simpson set it in.
The converter was replaced 5/14......

The wider direct band seems fine and the drum seems ok so far with just the pictures below.

Would you run that converter? If it’s only 5 years old.....the hub should be better and not crack but what do I know. That fluid being black.....Im thinking run it and inspect soon after.

The forward drum is shot. It’s worn down to finger nail catching.....is that shot? It’s too worn for me. I won’t run it. The other 904 has the 4 friction forward drum.....so I’m good on that.
What would cause that? Maybe bands not adjusted correctly. No one spends that much time in reverse.

Here is the magnet from the new transmission. The other 904 didn’t have one of these. I have 2 of them now. One was sitting it the van. So......why not run 2-

This doesn’t look good.....some metal shavings in the filter. I’ve never seen one so black. -

It’s a lock up clutch. I like this function as I’m just cruising this car.
What does the wire do? I grabbed the whole harness that went all the way to the fire wall. Might go into the fuse box.....I dunno-

Here’s an issue. The reverse drum is worn. I can catch a finger nail on it. It might be completely shot. -

a larger direct band. -

Fluid was pitch black.....and given that forward drum.....of course it is.

Hopefully this is in good shape. Or good enough that it won’t matter for what I use it for and how much it’s driven.

Gentleman.....I cannot thank you enough for teaching me and guiding me through all of this. I was gonna wait till pay day, but it could have been crushed by then.

All that’s left that I want to do is a mild cam and this build will be as far as it goes.....maybe 188/160.....but what would that really accomplish right now with the stock 76 compression.

I will hit that with the dial indicator and cc the heads to see what that is
You cannot use a forward clutch drum from a non lock up with a lockup. The sealing ring diameter in the stator is a different size.
By forward clutch I assume you mean the 2nd drum from the front.
They look identical but they are not. If you put a forward drum from a non lockup into a lockup trans you will end up with a no drive condition. It will assemble together, but the sealing ring diameter is .060 smaller on the non lockup drum and you will have a huge hydraulic leak. This drum is one of the fundamental differences between a lockup 904 and a non lockup 904.
