The Lesu 3 speed AWD trans showed up. It's aluminum and pretty heavy! Comes with two sets of mounts (one higher and one lower), but the holes don't line up with the width of the Tamiya rails. *sigh*
And look at the size of this teensy tiny press-fit pinion gear! I'm going to be feeding it with an 80t motor and a GRU so it's going to be subjected to a lot of torque. I'm concerned about it's longevity.
Here's the "highly detailed instructions" that come with it.
The rod at the top is if you want to shift the trans from the front, instead of the rear. I may have to look into this further. I opened up the trans and tried to swap them, but it wasn't look like it was going to be worth the effort so I may just shift it from the rear. And judging by the short length of the shifter linkage, they must assume your servo is right next to the trans!
Mocking up the trans with the motor. Adding the GRU will require it to sit rearward just a bit more to clear the servo. The GRU will add about 3/4" overall.
