tranny won't shift

[t-maxx_mumbler]

ok here I'm am again i have every thing good now i thinkbut my 2 speed trany only has one speed when its on the ground and running. but when i pick it up and run it off the ground it will shift no problem . I'm out of ideas on what it could be . any ideas ???? thank you

Well mine did the same thing... When Its in the air there is no load on it so the rpms will get higher than when on the ground trying to push the weight of the maxx around. I gave my shift point screw a 1/4 turn counter clockwise and its fine now.. Or your engine is running alittle rich.. just a thought..

I'm have'n a simular prob. it will run through first perfect but when it should hit second it just revs higher and higher. i took the trany apart and every thing looks fine. even the shaft the one way bearing is on has almost no ware. any ideas?
