Default T-10 identification assistance

Hello,

I was hoping that the collective could comment on the attached images with any identification thoughts. Specifically interested if there are any clear issues seen for the T-10.

Thanks in advance,

Joe

Thanks, Verne.. that's what I am thinking.. but the tail shaft housing doesn't have a date cast into it. I've heard that the very early T-10s didn't always have a date on the tail shaft housing, but I'm not so certain.

That should be worth some serious money to me! Anything on backside of the sidecover? My 58 7A tail had full date of "3 25 58" by this March 58 timeframe. Your tail being a "7" tail is so rare and especially since it was built on April 11 57 with or without a date.

What I find interesting is that the main case was cast almost a year before it was assembled.

I wonder why that is.. the cast date - is that based on the 3-20 from the label on the case?

Are you selling it or is someone else selling it to you? I'd like to see the back of the side cover, if possible.

Everything on that T-10 seems to be about as early as you can get.

I bought this transmission.. so it's not for sale. I'm going to put it in my car as a replacement to the three speed that I have now. My research into this T-10 would indicate that it's right for my car and it seems to check all the blocks off for an authentic T-10. I am trying to keep my car original, so I thought I'd ask if anyone saw something I didn't know about. I'm fairly new to these cars, so it never hurts to ask.

I'll see if I can get a picture of the inside of the side cover.

Thanks again for everyone's replies. So far - sounds like I got the right T-10.

March 20th is not a year before April 11th.

Thanks for pointing that out as I don't know how I came up with a year early? Think I have been shut in too long maybe.

There would typically be a casting date inside the cover.

That would be for the cover only, right? I’ve seen the covers for sale individually that have the markings inside - this is an example (not my cover).. what do these markings mean?

The T10-148 is simply the casting number of that side cover. That one does not have a date cast into it as the one above does.
Could you post a photo of the left rear side of the tailhousing on your trans?

Verne,

That side cover I posted a picture of - that's not mine. My T-10 is in shipping now and on the way to me. I've reached back to the seller to see if they had a picture - should hear back on Monday. The above photos are all I have for now. I'll see if I can get any other ones.

Thanks again for everyone's look at the trans - so far it seems like I may have gotten what I was hoping for.

Joe

Joe,
Just so you know, I've compared everything I can see on your trans to what I have documented and so far, and yours appears to be 100% legit. I have recorded another '57 case cast on March 20th and two tail housings with mid April casting dates. It's not uncommon for some early parts to be missing casting dates. For instance, several early '61 T10-1C aluminum cases lacked a casting date.

I have never seen a T10-7 or a T10-7A extension without a casting date or without a "S.P.A.C." casting foundry mark. Just for curiosity, when it arrives, check to see if the case, extension and side cover have all been painted.

I'll be certain to take more photos and see what it is that I've gotten myself into.. I'm happy to have this community to lean on for information. Seems that there are some folks out there that will try to earn a buck off someone like me for parts they know may not be what the person buying them expects. I'm not saying that this is the case for the T-10 that I've bought - just my experience so far has been that two people selling the same parts will tell you that the other person is selling counterfeit parts of something they know isn't truly legit.

My feelings on the matter are biased - I am an active duty military member.. and I love my country. I have served for almost 30 years. I've scrimped and saved so I could buy my piece of American history.. only to find that there are people out there who try to mislead others so they can make money.

I certainly hope this isn't the case for this T-10... seems like it's not. In my quest for this transmission I have run across people who are members of NCRS that offered to actually re-cast parts so they appear to be numbers (or date) correct in order to sell me a T-10. This particular one didn't do any of that.. the transmission has been rebuilt and as you can see it has new paint. It looks like the main case is unpainted with the tail shaft case being painted a silver color.

Don't know if this all makes sense, but I do appreciate the knowledge of those on this forum. I just hope I didn't make a (several thousand dollar) mistake.

Thanks again..
Joe
