On your XXX dump the Losi washer setup in the dif and go with the AE spring from the GT trans. Remove the washers and replace them with the time proven AE pressure spring. This will eliminate the constant re-adjustment and nut stripping that the Losi transmission is so hated for.
Install the spring, Slowly and carefully tighten the spring until you feel it **just bottom out** then back it off 1/8th of a turn. Check it again after 1 tank of fuel. It should stay adjusted until your next rebuild. You will still need to check it as a matter of routine maintenance.
I hope this will help eliminate trany frustrations of my fellow XXXNT owners.
