I am going to change my primary, trans, and crankcase oils. In the past i have only change the primary engine oil (as i understand it, correct me if i am wrong) Does anyone out there know the intervals for changing oils. After 3000 miles i try and change the primary oil and filter. But am unfamiliar with the other two. What precautions should be taken? I just ordered i service manual today from the harley shop in Seaford deleware (tax Free : ) for $60. Are the better deals out there for 2001 softail Deuce???
