Transmission wont shift.someone put a reverse lockout in it.the local hobby house put a drive hub assembly still wont shift.its like its in 2nd all the time.

Might have a stripped gear or might just need a new tranny

It might simply be the way shift point is adjusted - adjusted to shift really, really early. Makes it seem like its always in 2nd.

Check your tune that has alot to do with the shifting also check the tmaxx forum on the traxxas website theres alot of help there .

Use your air compressor to spin up the tranny and listen for it to shift if it not shifting readjust andspin it back up [with air] and listen for it to shift. Hope this tip help got if from Traxxas Support if all fails call them and they can tell how to trouble shoot the tranny GOOD LUCK
