I should have also asked what sort of machine that this tranny is being installed into?

What we have here

is a 1956 O.D. slated for installation into a T Bird and some Mercurys.

The T Bird tranny was adapted from the Mercury.

The Ford part # for the yoke you need is

B6S4841-A

Hope this helps

I have 2 T-89's the truck version of the T-85. One has a spicer yolk and the other one has a slip yolk. Mine is broke but it's a 31 spline. It's good to know a C-6 will work. My main problem is I need a 6" input shaft as mine's 6 1/2. I think T-10 stuff may work too. I'd trade my 2 T-89's for one good T-85. One of mine is a short tail shaft and the other one is a long tail shaft. One is basically a parts tranny and the sun gears are shot ..

Thanks Oldmics.

I was going to install it in my '55 Sunliner but I've desided to use it in my '29 Model A Roadster behind a Y-Block.

What numbers indicate 1956?

Just the fact that the R11-1 E and also the R11-1 H were 1956 installs only for both the Merc and T Bird according to my documentation.

Thank you very much...Mark

In fact I'd trade them for a good T-86 that would bolt right in ..

To anyone interested, I just received a yoke (from a C6) for my T85 (passenger car) and it fits perfect.

ebay item #190296112754

Here are the numbers...

These are new slip yokes for Ford C-6 transmissions,

they have been sandblasted and sprayed with a rust preventive coating.

2-3-3131X

1310 Series u-joint

1.390" 30 based on 31 spline

1.685" ground hub diameter

1.150" counterbore

6 9/16" U-joint center to end

After a gift certificate from paypal, I paid a little less than $10 altogether. This is a nice piece.

I just check Ebay for a 16 spline yoke and found one for a Fordomatic, so I check my Ford Chassis Parts catalog to see if it would interchange with my Heavy duty 3 speed OD "T-85" and sure enough the Fordomatic and the heavy duty 3 speed have the same part number. can anyone verify this? 

What p/n are you talking about. 49-55 used the same Yoke except for the police intercepter. 56 was still 16 spline,but some used a Spicer joint and some a Mechanics. I have a Hollander for those years and they are pretty good in showing what fit in the real world.
