Hello, yes, all gears should go through a break in procedure. You will need to go on short trips (15-20 miles) then let them cool down. Avoid an long distance trips for the first couple hundred miles. No towing for the first 500 miles. The oil should be changed after the 500 mile break in period.

Thanks, Ron
