AM Shifter (Gen 2)

Yes, the price has been raised. So has the content. Now included with all AM Shifters are 250-count optical encoders and a servo shifting mechanism. Therefore, for $20 more, you are getting 2 packages that previously cost $85 together.

 

This transmission is a slight variation from the AM Shifter. Two differences are present:
1. The two side plates are different from the AM Shifter, as more holes are present on the Gen. 2 Motor Mount plate.
2. The transmission is taller by 1/4" and shorter in length by 5/16".
