Sealing up the C6
Sealing up the C6
Spent the better part of the day pulling her out yesterday. What a process. Got a couple Q's now.
The entire housing is caked in oil soaked dirt. Both cross members were coated in an inch of the stuff. It was so bad that the stuff kept falling every time I touched anything, I got tons of it in my eyes and I was rolling around under the truck in it. I had to throw away my clothes. Anyway, it looks like oil has been leaking from the top rear of the engine. I'm thinking valve covers at a minimum. I put new gaskets on them a few weeks ago so I know that leak is stopped. (Q1) Can the intake manifold leak oil? I didn't think oil flowed through it but I guess I'm not sure.
I pulled the torque converter out. Looking into the bell housing there's a big ole plate held on by 7 bolts (not sure what the plate is called). I have the gasket for it. My question is: (Q2) can I just remove and replace or is there a process I need to follow so parts don't fall out all over the place? I don't want springs and bearings jumping out and bouncing all over the neighborhood.
And lastly, I have a power washer I can use to clean the housing. (Q3) Should I do it or do I risk damage?

But on a C6, it's made as part of the transmission case.
C6 flexplate retained to the converter with 4 special locking nuts that should not be reused. This C6 360/390 flexplate (C5AZ-6375-D) is also the same as 352/MX Cruise-O-Matic.
378941-S441 (replaced 378941-S78) .. 3/8" -24 Flexplate to Converter Lock Nut / Available from Ford. Same: Ford-O-Matic - FX/FMX/MX Cruise-O-Matic - C3/C4/C5/C6 - AOD - E4OD and etc. etc. etc!
Are these the nuts? https://www.ford-trucks.com/forums/1...late-nuts.html
Good to know. I have a new flex plate. The old one was near toothless.

See my post #4 in this thread.
And...see my post #2 in this thread.
You won't need C6AZ-7086-A unless you separate the extension housing from the case.

Do NOT reuse the converter lock nuts over again! Within the treads is a nylon insert, that wears down when the nuts are removed.
If used again, the flexplate will begin to wobble on the converter, make a knocking sound...because the lock nuts have lost their effectiveness to retain the flexplate in place.
Knock knock, who's there? Nuts. What nuts? Worn converter lock nuts.

Stand the transmission vertically or hang it from an engine hoist to replace the pump"O" ring and gasket. The best way to clean the outer case for me was a couple cans of oven cleaner. Good luck
EDIT: n/m . . . got it. I just put a coupla Vise Grips on the casting ribs and put a slide hammer on it and slowly pounded it out. It's about ready to go back in.
