I replaced my Diff's and I dont know which way the tranny output shafts turn, when going forward. right now I can turn both rear wheels forward by hand and the shafts that connect to the tranny turn counter clockwise. Is this ok? If not is there a problem with just running the truck in reverse to make the tranny turn the correct way.

If it is not spinning correctly you have put your diffs in backwards most likely.

Take your body off and look at the chassis from the top. When looking at the front diff you want the largest part of the diff to be on the right as shown below. The rear diff has to have the large part on the left side of the chassis to make the front and rear wheels turn the same direction.


To answer your other question, when looking from the front of the T-Maxx, the motor rotates counter clockwise so the spur gear will rotate clockwise. In forward the transmission output shafts will also rotate clockwise and with the ring gear to the right side of the pinion in the front diff this will make the tires move the truck forwards.

The reverse gear ratio in the transmission is lower than forward so if both diffs are in backwards you could run with the trans in reverse but your truck would be slower and have more torque at take off which could cause more wheelies.

Ok thanks a lot I check everything looks good.
