My brother has a Tmaxx and I just bought him a picco engine, we ran it and broke it in, and then today it ran out of gas, and after we filled it up, it will run great but the truck wont move! We checked the spur gear and everything seems right it just spins?

Which Tmaxx? - Trans in the newer one is diff than the older ones. Is trans case gray or black?

Could be you've broken something in the trans, but there are other things that would cause it not to move. Have you checked the slipper?
