Re: AA Transmission
Here are some pictures of the two transmissions and clutch housings side by side.
The 4-speed is considerably larger and heavier.
The u-joint is also different as the output shaft of the 4-speed is larger than the 3-speed. So you have one end with a large spline and the other end has the smaller A spline to mate with the drive shaft.
The last picture shows the different clutch housings.
1st gear is really low. Great for loading onto trailers and parades but for the most part I'd start out in 2nd for normal driving.
I replaced it with a 3-speed.
