Pricewise, it is $273 for the AM Shifter with the 2nd set of gears and pneumatics, or $360 for the Sonic Shifter (gears, pneumatics). Does the Sonic Shifter provide all the range typically used (assuming a complete set of gears)?

The basic setup of the transmissions allows direct drive by CIM motors, or through the AM Planetary Gearbox. If you use the gearbox, you would need one for each motor. Can you put a gearbox after the Transmission? That would be one gearbox per Transmission, rather than two.

If we can put a gearbox after the transmission, we can reuse the gearboxes we already have. Then the AM Shifter is all we need to choose between 1.56:1 or 4.00:1 ratio between low/high gear.

Summary:
1) Does the Sonic Shifter, with a complete set of gears, provide the range of ratios typically used?

2) Can you use the AM Shifter with a gearbox after the transmission?

If the Sonic Shifter (with a complete set of gears) provide the typical range, then that might be the way to go to reduce space and simplify construction.

Any other words of wisdom?

Thanks.
Well, sure, there's nothing in the rules (or physics) that says you can't. However, keep in mind that additional gearboxes = more weight and more moving parts = more likely something is likely to break. The Sonic Shifter looks like it has the same shifting options than the Super Shifter plus some.

Pardon my ignorance, but I'm not entirely sure what you mean about need a gearbox for each motor. You only need 1 SuperShifter for each set of 2 motors (generally 1 gearbox on each side).
