changing the gear oil after 10 hours will make sure any break in particles get removed. a magnetic lower drain plug is a good thing too.
most important dont grind the gears while shifting,. shift crisply, dont pussyfoot around. dont ease into it get, one quick motion . if not the gears will wear fast, and the more they wear, the faster they wear.
One cluck is all you should hear.
JESUS CHRIST IS THE WAY, THE TRUTH. AND THE LIGHT. !!!! PUT ALL YOUR TROUBLES IN JESUS HANDS, YOU WILL SEE WHAT HE CAN DO.
