More 65 ALumn t-10 questions (sorry)

There were 3 T-10 tags in 65 Hek-R, Hek-V, Hek-M. There are two close ratio second gears possible 2.36 M ratio cluster 29,25,20,17 T second gear 29 T, 2.36 J or L ratio cluster 29,23,19,17 T second gear 30 T. Hope this helps.

 

The tags I have not been able to figure out. The M and J/L are different ratios in 2nd and 3rd gear. Both have a 26T maindrive (input) and a 36T 1st gear. The M has a 29T 2nd and a 27 T 3rd, the J/L has a 30T 2nd and a 29T 3 rd. The clusters have to be different to accept the different 2nd and 3rd gears. M cluster 29,25,20,17 T, J/L cluster 29,23,19,17 T. If you get an explanation on the tags I will add it to my T 10 info sheet.

 

Hi,
If I don't recall wrong that T-10 was assembled on
April 29, 1965. Could have fit my 65 perfectly.

Hi Roger,
The aluminum one. Saw it in ebay myself but my friend bid on it
so I didn't. My 65 Sheby 5S275 was assembled at San Jose' about
May 7-10 and the assembly dates on the T-10 and the car
are normally pretty close.

Like to say thanks a million to this site which made it possible for
me to get in contact with Roger (fastback272) and buy a correctly
dated BW T10M1 for 5S275. The one I have had in my car for 19 years
is assembled on July 8, 1965 which is more than two months too late.
Got it and it has the correct gears (2.36 on first), side cover etc.
Also, thanks Roger for parting with it.
A very happy Texas Swede

 

Hi,
The T-10 M1 dated D295 2 or April 29th, 1965, second shift
is now rebuilt with all new M gears by a friend of mine that
is a master with transmissions and rear axles.
Later this week it will replace the T-10 M1 currently in my car.

I sure hope Rusty dosen't read this. He might get the big head. Good luck with the install.

That's great you have the right one now.
Question for the list members: The T10 M I have for # 17 does not have a tag, and I am not even sure what it would look like. Anyone know which tag, where it would be attached to the Trans. and how I can find the right one?

Mike

 

5026 has the original transmission with no tag. I think that if the date code on the trans case and tailshaft is earlier than your car was built, (Which I am guessing was early Feb. 1965) you are home free. I wouldn't worry about the tag.

 

Hi Mike,
These are my observations over the years for T10-M1's.
Never seen any with a tag.
Early 65 to mid production #300: No casted date on neither housing nor
tail shaft. My new trans has none.
Late production 65 # 400: Casted date on housing but none on tail shaft.
Have seen several over #400 with this like 4-12-65.
66's: Casted date on both housing and tail shaft. My current one
has 6-9-65 and F-7-65 respectively.
They all have an assembly date just behind the side cover. See picture.
My current one has G85 2, July 8,1965, Second shift. My new one has
D295 2, April 29, 1965, Second shift. This is exactly five days prior to my
engine assembly date. My friend has two in the #400 and both has three
days between the trans and engine assembly dates. Both are original to the
cars.
All has a date code on the side cover as well as a date code on the adapter
plate (not visable when assembled)
