Inspection of a 904 torqueflite


Haven’t taken out the front servo yet. I’m sure there is some black funk in there as this seems to be a place where the fluid doesn’t cycle as much. The back servo had very little of this though, so maybe this one won’t-


The output shaft rides in this piece. There is a wear pattern on the aluminum. Is it worn out? I don’t know -


This is a tail shaft bushing. It looks steel. It has some wear patterns and looks eaten up in some places -


What the fluid looks like with friction material in it. This was in the bottom of the pan-


Another of the tail shaft bushing-


accumulator housing.....do these wear?


This bolts to the back of the main transmission housing. It has wear patterns. There is a picture of it above as well. It’s all aluminum. Do these typically get replaced?-


Main housing. That’s where the overrunning clutch goes. There are large needle bearings and springs. I’ve seen where people replace the springs and bearings but leave this part in there?-


Valve body......black coating is friction material fluid that leaked out when I turned it upside down-


Rear servo arm pin....housing. The pin that holds the servo goes here, there is a wear pattern -


The pin had black film on it-


Rear servo piston-


This is the forward clutch drum before I took it apart. There is wear on the bushing.....but I don’t know if we replace these when they are like this or not. The clearance is shown between the clutch packs and the snap ring. I’ve heard this is measured with a feeler gauge. I need to know about this-


This pin is for the rear servo arm. That o ring leaks and goes out the tail shaft seam. It’s rare the or ring leaks but I’ve heard when it does it’s hard to track down and the tail shaft has to come put.
You screw a bolt into the back of this pin to get it out. It slides right out and the tail shaft is what hold it in there-



That’s all I have for this. I have not taken apart the front pump yet so I don’t know what that looks like. I know the bushing that the converter rides on it eaten up but that was brim a cracked torque converter hub which is common with these 904 transmissions.

I could have just pulled the pump and put a new bushing in there and maybe gotten some Mike out of it. I figured the transmission was not far behind and I didn’t know what had ever been done to it.
I can say that it was painted ford blue so it has been out of the car.
I can’t say if it was even original to the car. It was out of a 318 76 charger.

I won’t be driving this car much. I don’t really drive the car hard at all and don’t need performance parts. Maybe a shift kit.
