AOD rebuild

[1970Custom]

So, I'm swapping a 351c into the '70 and I don't have the $$$ right now to pick up a TKO600 like I want so I'm just going to rebuild an old AOD that I had in the '70 originally, only problem is I toasted either one or both of the pumps in it and I want to know if they can be rebuilt or do I need to be thinking replacement??

Either way where can I find the parts? I've been able to find a few pump parts online but no luck when it comes to the pumps themselves...


Thanks,

Yes...you can rebuild it. I am half asleep tonight, but I can get you sources for parts and the book when I am awake. I just made it home from work and for once...I will sleep well.

I posted it all on the NWU in one of the threads a while back too.

When you hear people saying the AOD is weak, what part(s) is it that always break?

 

[Brian_B]

I am not aware of that. I have seen quite a few of them (in my family) go over 100,000 with no issues. Maybe..they don't hold well in high HP hotrod situations? The ones I have dealt with were family type cars.

Parts..rebuilt front pump, rebuilt torque converter, a rebuild kit (contains clutches, O-rings, and other soft parts), bands (not sure how many are in that trans), thrust washer kit, bushing set, Front and rear seals (if not in rebuild kit), filter and pan gasket (if not in kit).

Before you order any parts get an ATSG manual from NAPA auto parts. Or...order it from www.atsgmiami.com

It will cost a few dollars more in shipping, but either way it should be less than $30.


A real ford rebuild book is better, but hard to come by. The ATSG are fine though. Dad has one professional (don't ask how he got it) MOTOR brand rebuild book for fords. I think that is one of the best ones ever (real old).


Once you have the book then order parts.

This is where we used to order all our parts. Sometimes I went and picked them up and sometimes we had them shipped. They have everything in stock (warehouse in back) even the little shifting grommets on an old C5 or something.

They have warehouses all over the country though. Either call the toll free number and ask or do a web search.

This is not where the typical shade tree mechanic gets parts. Professional mechanics deal with them most of the time. A friend of ours in the business hooked us up with the name. You can find discount parts on evilbay, but not the same quality.

ANother question, what is the difference between the 28oz and the 50oz flex plates?

Just a guess...I think different engines use different ones. I have always just replaced them with what was already there (if they were damaged), so I am not sure.

the one for the 351C I just picked up went with the trans so I'm trying to find a new one, on evil bay I've found both the 28 and 50 oz flex plates and both say they will work with my engine...

It was based off of production build date, If I recall correctly, the newer ones were the higher imbalance, but i don't know absolute, as well as when they made the change.
