3-Speed Manual - 1977 Sportabout 232

It's a 150T and a very nice 3-speed manual. Improvements over the earlier AMC 3-speed transmissions are that the 150T is fully synchronized in all forward gears and has a wider spread of ratios. 2.99 first, 1.75 second, 1.00 third, 3.17 reverse. This allows it to be used with lower axle ratios to reduce highway engine RPM without compromising acceleration at lower speeds or clutch life.

A 150T with a 2.73 is very nice. I briefly drove a 1976 Hornet with a column-shifted 150T and a 232 I6 and I enjoyed it very much. That was the last year for a column shift manual. Everything went (barf) floor shift in 1977. 

In Jeeps the T14 3-sp came behind a Buick V6 or an AMC straight 6.  In Jeeps the T15 3-sp came behind the 304.  I believe a T14 would bolt up to a 304, but I wouldn't count on it staying there for long if you drive hard at all.  The T14 was probably not really that durable behind the V6 or the 258.

I have no idea what AMC did for transmissions except for Jeeps.

72 was the last year the T-96 was used, and it was a special AMC only "heavy duty" version (slightly larger input bearing and harder shaft and gears). Only used in the budget model Gremlins and Hornets. Some serious penny-pinching! All the other cars with six got the T-14.

The only problem with three speeds (stick or auto!) is that there aren't enough gears to make the motor real happy! That's why you build a torque motor for street use, wide torque band means you can better use a three or four speed. Five or six is better -- keeps the engine in the higher torque range more and makes it happier to do it's job.
