NEED HELP!!
 

so i swithched out my 3.3 out of my t-maxx w/ an o.s. .18 cant get the new motor to keep running, and this is where i really need the HELP, while running got it stuck on a dirt hill, just strted to run WOT for no reason then it just locked up, but not the motor still turns over, seems like the front a rear diffs still work, when i hold it in the air the front and rears turn the opp. ways, but when i set it on the ground to roll it forward its just locked up, before i start ripping this thing apart and sugggestions from u guys , did i blow the tranny

sounds to me like a diff is backwards, I done this the other day on my revo and it was doing the same thing

ripped the traanny apart, theres the problem the tranny gears were trashed

are you sure that you got the on right .. that would make the center diff go...

say what?? brand spanking new truck, motor was junk didnt last long ,all i did was switch to the o.s. .18
