He is right. Even thought the directions might not be as speciic as the new tmaxx and ntc3, it still should show and explain how to breakin your engine.
As far as your 4X4 deal. I dont quite understand the problem. You something like it got loose and wouldnt spin anymore. With my nrs4 2, the diff's do lock up very seldom. It only does that if it spins out or something crazy. Just give it a push and it will be good again. If your wheel has too much play, tighted the wheel nuts using the tool provided. Make sure you wheel nut and pin in in snuggly too. If any of this fail, check for ANY rocks, trash etc. BTW, before u do this, read your entire manual twice.
