I'm having the same problem with my maxx right now, it won't switch from 1st to 2nd. I've tried everything from loosening the 2-speed adj. screw (which makes it shift sooner) to tightening it which of course did nothing.
The 2-speed adjustment screw is the offset grub screw that you can see through the access hole in the tranny case. You have to line it up to access the screw, I'll try and see if I can describe it.
-Open the access plug on the tranny case and look into it with a flashlight
-Spin the spur gear while looking into the hole until you see a notch that is cut out
-HOLD the spur gear and roll the truck on the ground (while looking into the hole) to reveal another grub screw
-Loosen the screw to shift sooner, visa versa...remember the screw is sideways so you have to access it like that (if that makes sense..lol)
