Re: [Amc-list] Overdrive offerings.../327 Twin-Stick?

[Frank Swygert <farna@xxxxxxx>]

As far as I've been able to determine Twin-Stick was AMC unique. I've got books on other cars but no one else seems to have "split shifted" the OD units, not from the factory. 

There were V-8s with Twin-Stick, at least in 65 and 66. The TSM indicates the T-85 was also set up with the wide gear spread for Twin-Stick. The T-85 was normally used behind a 232 or 287 in big cars, the T-89 behind the 327. 65 was the last year for OD behind the 327. The T-10 four speed replaced OD behind the big engine in 66. So as far as I can tell only the 287 would have got Twin-Stick from the factory, unless the T-85 was used behind the 327 with T-S. It would stand up behind a 327 for a while, unlike the little T-96, which was near its limit with the 196! Remember, AMC had a special heavy duty version made (the T-96J) with a slightly bigger and harder input shaft for Gremlins and Hornets with the 232.

Was AMC unique in offering "Twin Stick" overdrive? I know there were many 
variations of drive systems other than straight up manual or auto 
transmissions (Studebaker Hill-Holder, E-stick, etc), and overdrive has 
been around nearly forever, but how many of them are as interesting?

I used to think it was just a marketing gimmick, eg. a lever instead of a 
pull cable, but when I got this car and looked at the TSM it's obvious some 
thought went into it.

The Twin-Stick hack is pretty nice. It involves a lot of convoluted logic, 
and it looks like it could be very confusing when it goes wrong! (Stalling 
upon accelleration, stall at over 28mph, ...!)

AND 

It's my assumption that one good hole shot from a 327 would eat every gear, one by one, in one shot.

As far as I know, in that year (1963) the T96 was the only trans to get OD and especially Twin Stick. Is this incorrect?
