been a while but im back lol.so i was taking my son out the other day for his first nitro experience and when driving on the street it seems to be just in 1st gear and revs high and if its in short grass its doesnt move well and mostly it wont move at all in the short grass,it will rev and thats a bout it,not sure if its the clutch set up or what.its brand new but perhaps i missed something.theres only wear on the top and bottom of the shoes everywhere else still looks new.
Trucks tmaxx 2.5r doest move well if at all in short grass

Incredibly late reply, apologies. This sounds like you broke the pin in the transmission, or the transmission is not engaged fully. Could also be a very loose slipper clutch as well on the spur gear.
In the video below, at 3:03 I pull out the main drive assembly from the transmission and I say "show you this gear". Well, if you pause it at 3:03, look at the left gear, there is a pin. This pin is known for snapping causing high revs and no power getting to the ground. I would 100% check the slipper first, but keep this pin in the back of your mind. And if the pin is broke (sheered is the correct term), then you likely need to back off on the slipper and let it slip for about one second when going WOT before it hooks.

slipper clutch the nut tends to back off it won't move very well or not at all.

Try using some blue Loctite
thank you for the help guys,ended up flipping the shoes around and it seems to work.Now for the new problem,the idler gear bearing seal came off and detroyed the gear it runs with,im not to sure if i want to throw another 5116 bearing in this thing and have it possibly fail,is there a better bearing out there for this?
thanks again
thanks again
Kyle9993. Just my 
but I would just order the same bearings. Something else could have destroyed the gears like missing teeth or something. It's a nitro. You bound to wear or destroy parts.

If you had metal shielded bearings, you can go with the composite or rubber shielded bearings which would do less, if any damage to the gears. Just look for the bearings that are not silver where the shield is. If this is inside the transmission, you don't even need the shields so you can run without them. The shield is there to keep dirt out, adn the transmission is sufficiently sealed.
