63 T-10 tranny value

[Jim S.]

This is a bit off topic , but I know you guys will know !

My Neighbor just asked me if I was interested in buying a T-10 Tranny . He has no idea what it is worth and neither do I .
He does not want it , but it came attached to a 327/340 solid lifter rebuilt motor he does want. It is supposedly rebuilt as well !

The following are the markings I could find and as best I could read :

MAIN CASE : T10D-1

TAIL HOUSING : T10-7D
GM 3813490
10-2-62

INSPECTION COVER : 9-12-62A

BEARING RETAINER : T10C6


I am going to take a wild guess here and say it is for a 63 based on the two date codes I found ?

So guys, does he have anything worth something , and if so , how much something ?

This trans could be worth 400 to 900 bucks, or even more after a rebuild. One would have to look inside to nail it down. Does he have rebuild receipts? Depends who did the rebuild. (I did my first one myself in 1966, pushed it up into my '62 Impala, and headed out on our honeymoon one week later!)

Re: 63 T-10 tranny value

The 63 transmissions (both T10 and Muncie) are a ONE YEAR ONLY tranny. The MOST siginficant feature of the 63 trannys is the front bearing retainer. It has a smaller diameter than the 62-earlier or 64-later trannys. Thus, the 63 trannys ONLY MATE to a 63 bell housing------------------again, a one year only housing.
In my book, they are ONLY WORTH what someone will give for a correctly dated 63 tranny.

Re: 63 T-10 tranny value

you can lways change the front bearing retainer to the large one and it will then fit the more popular bell housings

Doug,
Unless it is a aftermarket retainer, the bolt pattern on the trans is different.

Cary, Tom and Dom,

Not knowing the history on 63s, I did't know what you were talking about .So I did some searching on the archives and found out that the" 63 only" bearing retainer is only 4.175 inches wide, while the more common retainer is 4.675 inches wide .

I asked my neighbor to measure his , and it is indeed 4.7 inches wide . So it appears that it has been changed to a wider bearing cover . It is still a T10 cover however, as it does have the T10C6 on it . For whatever that information is worth ?

As for the rest of the answers , I guess it is only worth something to someone with a early 63 , and not much more valuable than a decent Muncie to most , if I am reading these answers correctly. I guess the best I can do for him and our members , might be to list it for sale in the drive line to see if anybody needs one .


Thanks guys for all the input ,

Jim and all

If this T-10 transmission happened to have been installed in a 1963 passenger car ( Impala, Belair, etc. ) with a 409 cu in engine, it would have the larger front bearing retainer as well as the larger bearing. The 409 engines retained the larger front bearing as used in 1961-62 pass cars and Corvettes. All other 1963's, pass cars and Corvettes, used the smaller front bearing as previously discussed.

Ray,

If it's a T-10 D case used in 1963 even if installed in a 409 the front bearing is the small diameter.

Jim, one thing you could find out is if it's a close ratio or wide box, the wide box has one groove on the input shaft.

Re: 63 T-10 tranny value

Tim ,

I sent you a PM.

As to anyone else who cares : No Notch in shaft ,and reportedly a close ratio box with new bearings and synchros.

T 10-C case is 1962 vintage, not 1963.

Re: 63 T-10 tranny value

Hi bill,

It Is a T10 D case with all the date codes in late 62

That would be a nice piece for an early '63 car.
