T10 M 4 speed transmission tailshaft ?

[papa scoops]

like zray, my car was Shelby built around the same time (s1122) feb 66 (both ford and Shelby build) and it has a iron tailshaft. the delivery time between dealer and original owner was most likely to short of time to replace under warranty, and oo never mentioned anything about it being replaced, but you never know. I will try to visit him today and quiz him. I've had it since the early 70's. phred

Like S1117 and S1122, S1134, also a February 1966 SAI build has an aluminum case and cast iron tail shaft.

   Zray , scoops and greekz ,
      Those cars produced in your range did have the alum case iron tail. This is what "I' call the "transition'' transmission. Aluminum tailshaft housings were prone to cracking in racing applications and were changed to iron which prompted the aluminum / iron trans. Some of the SAI catalogs show this combination for sale. By using date codes on the aluminum cases , "I" have the opinion that when the aluminum main cases were used up the iron main cases were used and the cars after 1300 or so and up cars had them. Most of my information came from conversations with Ray Wolfe( rip) of SAI and HP Motors. He was a wealth of "tribal knowledge"

Add 1114 as well

It is documented as to what was supplied with the vehicle when delivered by Ford to SAI, those are facts. Anything else in place of or deviated from original can be interpreted as a "day 2" modification, it does not matter if a Ford dealership or an owner did it.

I was not trying to justify that if a Ford dealership installed or repaired the transmission in any other way than "as delivered" that it could be interpreted as being original.

+1 . I am glad to read that I mis understood your intentions.

how many of our 1100+ cars are nickel gears? phred

From the SAI parts catalog, dated 4-1966. Strange how that ad clearly states that the transmission case and tailshaft are of aluminum but you can clearly tell that the tailshaft is something other than aluminum.....

Thanks for sharing that scan.

It looks just like how the T10 in 6S933 was restored:

  Nice work Brant.

Please excuse me if I "horn in" on this thread but it relates to the T10M subject.  I happen to have a spare T10M, AL case and tail.  The case has a casting date of 7-27-65 and an assembly date of K45 2 (Oct, 4, 1965, 2nd shift) and a tail casting date of 8-27-65.  Can anyone give me a range of 6S VIN's for which this tranny would be correct or suggest when it might've been installed?

 I'll hazard a guess of '66 carryover through roughly 600 in '66 based on production dates. Too late for a '65 IMHO. Others may have a more narrow window.

I would think that, since they were carryovers, they would've been assembled at San Jose' before the usual late August '65 shut-down.  If that were true, this tranny wouldn't have been installed until much later.

Randy,
The original all aluminum T-10 in 6S923 has June and July casted dates and an assembly date of Dec4, 1965.

You're probably right. I honestly don't remember the dates on my carry over trans.

   Texas Swede ,
         Good to know those dates.
