Hey guys new to the mts been racing quite awhile and just wanted something to bash picked up a used tmaxx and the front wheels go in reverse and the rear wheels go forward. Took the tranny apart and everything seems fine but I'm sure its not any advice would help thanks in advance

One of the differentials is in upside down

You mean I should just flip it over

Yep. There's a little collar on the front of the case that indexes it in the bulkheads. Rotate it 180, and reinstall. take note of which way the screws are facing for future reference.

Thanks guys do you know an easy way too adjust my second gear

Or I should say a certain amout of turns to set it

i will try my best. you will need a 2.0 hex wrench. 1. remove the large rubber plug from the trans housing. 2. Look into the hole and rotate the spur gear until you access the hole in the aluminuim drum is visible. 3.hold the spur gear and use your finger to trun the primary gear shaft which extends from the trans housing. trun it clockwise.you will see two set of screws pass by as you trun the primary gear counterclockwise. the first set screw holds the gear in place dont loosen that one. the second one is the 2 speed screw that the one you want. 4. trun the set screw trun the screw clockwise to raise the shift poit ( takes longer to kick in ) trun counterclockwise to lower the shift point to an earlier shift. Dont loosen or tighten it too much you may pull the screw all the way out and have to take the tranny apart to reapair. i Have mine set to hit second gear right away and still have wheeelies like crazy. Good luck
