Unhappy Brand new NITRO 4TEC 3.3 (Engine works spins, wheels dont work?)

So i got my brand new model 4807 traxxas nitro 4tec yesterday.
This morning I went to begin the break in procedure. I followed all steps accordingly except ONE! I forget my body at home for steps 2 thru 5.

In the middle of step 4 on my full speed 3 second or so passes (Not letting it hit 2nd gear, although once or twice it did) the wheels stopped responding. I pressed the gas on the controller, and the engine worked, the belts spin, the exhaust/resonator or whatever you call it spit out blue smoke as usual, but wheels, nothing.

Also now Im having problems starting my car and keeping it running, it starts, then 2 seconds later shuts off. I changed the glow plug and air filter but no help. Im guessing its the idle or high speed needle or something not sure, but that I can fix.

IM MAINLY concerned about the wheels not responding anymore. What can be wrong? What should I look into, I dont wanna take anything apart that I dont have to.

Please help.

PS: Heres a video
