Re: [Amc-list] Breadbox American 440H with Twin-Stick

Tom, you need a synchronizer! It's a "dog" type with three pop-up "dogs" that engage first to get things at the same speed. Sounds like you're missing a dog! It's only a matter of time before one of the others go, and then the third will likely jam it in 2nd or 3rd shortly after. 

Rebuild parts are available. The only thing you would have a hard time finding are the gears themselves (because of the Twin-Stick gap between 2nd and 3rd). The T-96 is a fairly common transmission for small late 50s and early 60s cars. Kaiser Jeep, Studebaker, and Ford also used them. Bearings, seals, and the internal "small parts kit" (which has synchros and other misc. parts) should be available through any manual trans parts place. You might have to go to an antique specialty house, but I doubt it.

The only problem with the T-150 would be the bell as far as mounting. If the front bearing retainer were the right size cobbling an adapter would be easy. Unfortunately I think the T-150 has the same size retainer as the SR-4 (and T-14 three speed??). It's a good bit bigger than the one on the T-96. I mounted a retainer from an SR-4 on a T-96 to make it fit a later model "universal" bell, but you'd need to machine an adapter ring to do the reverse.

The T96+OD in the American is definitely the weak spot at present. It's ill 
behaved when cold (hard to pull to N from 1 when declutched, makes a noise) 
and it internally locked up twice at that time (BANG! when I clutched 1 to 
N). I now baby it into N first few times in the morning. That's not good. 
Plus it leaks from all seals, a lot! It's getting grindier shifting 1 to 2 
(when cold) or 3 to 2 no matter how careful I am. (85W-140 in there, should 
be 80W or 90.)

If I can find the parts I can rebuild it, but I worry about finding the 
parts (seals, synchros, etc). The T-14 is tempting (I have one, plentiful, 
strong, I think it fits in the hole) but it would ruin this car to not have 
OD! My "spare" T96+OD I am pretty sure is not Twin Stick (big spread 2nd).

The T150+OD I have is wrong on all counts (input, bell, huge size, length, 
...)
