Wayne,
That part was changed to metal from aluminun and there is a TSB on the change as it addresses the same problem you are showing. This part may even be available in reproduction..
You definately don't want to skimp here..

I was able to find a steel one but it was to large.
Any chance this might be covered by warranty
Thanks TimComment

Well, if you found a steel one that was too large, then you didn't find the right steel one. There are a LOT more steel ones (actually, cast iron) out there that are too large than there are steel ones that are the size you need.
The cast iron one you need was GM #604932. Does that look like a strange part number? It should; this retainer was first released in 1939 for 1940 Chevrolet passenger cars and was last used in PRODUCTION for 1954 passenger cars. It replaced the short-lived GM #3790278 in August, 1963. However, the 604932 was discontinued without supercession in July, 1984.
I would think this retainer would be available in the replacement market. I'd call someone like Larry Fischer or Ed Hartnett.In Appreciation of John HinckleyComment

Re: Help t10 front housing 1963
The large O.D. cast iron retainer with the small bolt circle for the 207 front bearing was used in 1963 passenger cars with 409 engines, they didn't use a special bell housing like the 421 the Corvette used...
I know some one that would have both the Aluminum and cast iron retainers your looking for... Crash

This is from the gear box
It was made in both aluminum and steel in 1963, It was not used on any other models. Just the 1963 corvette.

The GM #3790278 retainer was used for other applications besides Corvette. It was also used for most 1963 full size passenger cars with manual transmissions except those equipped with 409 engines.In Appreciation of John HinckleyComment

If you have the wrong bellhousing (and you plan to continue using it), you won't need the 63-only retainer.
The thing I don't understand is how the retainer you have pictured worked if you have the wrong bellhousing. Did someone install a transmission with the aluminum retainer (i.e. small OD) into a bellhousing with the larger hole?In Appreciation of John HinckleyComment

Having personally looked through a massive pile of T10's and Muncies, you can with high certainty get that part from Tracy Performance, Roseville MI. A complete tranny too. Send a email if you need his number.Comment

Re: Help t10 front housing 1963
Yes . The new one will have the same bolt pattern and a larger dia to fit in bell housing correctly. I will keep the bell housing good shape. I guess
Bubba at work. Their has been more than one engine in this car over the years. It is what it is as they say. Thanks

Re: Help t10 front housing 1963
Mr. Lucia,
While casting about the internet for an inexpensive example of 604932 I exchanged emails with a gentleman who had several NOS service items from the 40's labeled 604932 but with casting number 591023 and made from aluminum. Is it possible or probable that 604932 was not cast iron in it's pre-sixties incarnation?Comment

The "saga" of the 1963-only transmission bearing retainer is a strange one, indeed. To be honest, I don't understand the "evolution" of this part.
GM #604932 is a part that goes back to 1940. It was used for 3 speed transmissions for passenger cars and some trucks. It is very possible that it used casting number 591023 because numbers of that series were used for many different transmission bearing retainers. In fact, I believe I have seen examples of this aluminum 591023 and wondered what they were all about. I don't know too much about these very early versions of the 604932, but I'd say it's very possible that they were cast of aluminum.
The 1963-only bearing retainer was GM PART #3790278. It was aluminum.
The GM #3790628 had a very short life. Released in the late summer of 1963 it was discontinued from SERVICE in August, 1963 and replaced by GM PART #604932. The latter part number had been around, as I mentioned, since 1940. I believe that the 604932 that was available at this time was a cast iron version and that version remained available in SERVICE until it was finally discontinued without supercession in July, 1984.
There are a lot of questions here, though, and I certainly don't have all the answers----maybe NONE of the answers.In Appreciation of John HinckleyComment

Joe,
Well, my 3790278 has seen way more service than it could handle so I will be buying a new cast iron part from one of the sources listed earlier. I just found it funny that I almost bought a pre-50's version purported to be "604932" that would have still been aluminum. Typical of my attempts to save a buck which turn out to cost more in the long run.
Thanks for the insights.Comment
