Inside an AOD torque converter
Inside an AOD torque converter
Time for an inside look at these AOD converters.
For starters I want to say that most of these components are completely interchangeable with 4r70w components. So lets see this thing already
Here is the pump on the outside
Here is the inside of the pump showing the fins. This is the medium stall (common) pump.
The high stall version looks like this.
The little difference in the tips of the fins makes about 200rpm stall increase.

This converter was in really bad shape. If you look closer you will see that the fins were very loose in it. I pulled them up for presentation. These fins being loose like this will give a ching,chang sound as you get on and off the throttle in first and second gears. This design bypasses the pump stator and turbine all together in 3rd and 4th gears.
Now you will see the wear plate (or 812 washer as it is called). This one was in very bad shape and will be scrapped. It's hard to see in the picture but this piece is worn and distorted very badly.
Here is the stator cap that rides against it, this was in very poor condition as well.
Here is a comparison with a good stator cap.

Here is a picture of the roller clutch, nothing is wrong with it. That is what I like about ford converters the roller clutches are almost indestructible. It will need new springs and rollers upon rebuilding, but it would works just fine as is.
Here is a picture of the stator installed in the pump.
Here is a picture of the turbine, notice the hollow rivets.
Here is the fiber washer that was in this converter, it is worn down to almost nothing and actually broke in the wash, it was not broken before hand or it would be roaming the transmission instead.
Here is a comparison of that washer and what it looked like when it was new.

Here is a picture of the damper in this converter. THis was the best design damper ford ever made, and still the strongest available. Even the aftermarket ones are just a duplication of this version which has been slanged "bulletproof". So much for that theory do you see the broken spring?
I took a picture of the outside of the front cover to show the bolt indentations where it ballooned out, but the flash got the best of the picture and it shows nothing. I will try again tomorrow.
