It's so weird that you even have this. The tail housing looks different than what I found, of course but so does that bell. I'm guessing it's because this was a version with the starter on the driver side? Did they change the bells for this transmission JUST because of the starter?

I have a T14 that has the side shifter. It came out of a 1972 Gremlin with the V8.

I am not sure what transmission came out of my 66 American 232 car, but I think I can find it. You can have it if you want to pick it up.

The truck T-14 has a different gear ratios than the T-14 made for the car.

The car T-14 has 2.64 1st gear and 1.61 2nd,  that's not much different from a 69 T-96, 2.61 1st and 1.63 2nd.

I had a t-14 in my 69 American with a 232,  it didn't seem to me to have any wide gap between the gears.

that's a 68? i think AMC passenger car T14, i think i got from pacerman (Joe). the bellhousing is from a 1963 Rambler American. so the starter is on the drivers side.

i admit i did google the ratios, but it was in fact a bear to drive. the car had a T96 with OD and a 3.77 (i think?) "big nut" axle. i swapped in the T14 and a Mustang 2.73 axle. top gear was a good match. but the engine didn't have the torque to pull 2nd for higher RPM than was reasonable.

the T96+OD and that axle was a great setup for that engine and car. the T5 is of course much better.

but now you;'ve got me curious, i will go out and put it in 2nd and turn shafts and figure out what gears are in there.

i'm wrong all the time.

I think the truck T-14 has a over 3.00 1st,  or like 3.10,  but the same 1.61 2nd gear.  That would be a pretty big gap between 1st and 2nd.

If you had a T-96 with the twin-stick OD, it had different 2nd gear ratios than the normal T-96.

My T-14 had a overdrive,  a special order car,  I've never seen, or heard of another like it.  I'm just assuming it's gear ratois was the same as the other car T-14s.  
A website devoted to Borg Warner OD's states BW never put their OD on a full sychro 3 speed,  but I had a sycho 1st gear,  and it was a T-14, because I had it out of the car once in that 18 years to replace the clutch.   I did it myself,  I saw the T-14 markings on the transmission,  I just don't remember the particular model # of the T-14.
 I drove it for 18 years,  if it did have a wide gap between 1st and 2nd, I either never noticed, or got used to it.

On my T14, I felt 1st gear was too high, and 2nd was too low. This was in my 1972 Gremlin. My 1974 Gremlin also has A T14. But the 74 has 2.73 gears whereas the 72 has 3.54s... I guess the 2.73s make a somewhat difference...

Hi, easy swap, just did it. The T-14 is twice the tranny the T-96 ever hoped to be. My T-14 came from 1971 Hornet. You will need a longer drive shaft made as the length of tail housing is actually shorter. Also MAKE SURE YOU HAVE a shallow bell housing to accept the 6.5” T-14 input shaft. Pilot, clutch plate, splines are the same. The speedo drive gear is different. Original was 7 tooth, the T-14 was 8 tooth. Got a 20 tooth “driven gear” and that will suffice for a 3:08 or 3:15 rear end. Use a 23 tooth for a 3:54 rear end. My little American has a floor shift……. Getting the original column shift rods to function properly may be a moderate challenge. Drove the car for the first time yesterday and WOW !!! I can shift into first without coming to a complete stop!!! 👍 message me if you need more details…….

Wow, old thread! Still good info -- I went back and read through it. One point -- the OD trannys all had the same ratios as the non-OD trannys. The one exception (I know of) being the Twin-Stick three speed, which had a big gap between 2nd and 3rd so 2nd could effectively be used with OD -- withoutthe gap 2+OD is about the same as 3rd). OD models usually have a lower rear axle ratio then non-OD. In effect you get a lower first gear AND a slightly higher high gear (3rd + OD).
