Last night, I changed to engine oil (mobil 1), trans oil (spectro GL-5) and primary oil (HD Formula +). The question I have is how much oil does the trans really need. The service manual indicated to put in 32 oz. and make sure the level is between the add and full line. When I added 32 oz, the level was low, so I added approx 2 or 3 oz to get the level correct on the dip stick. Checked on jiffy stand and didn't screw the stick in as the service manual indicates. Is it ok to add the extra oil in the trans to get it to the correct level? Haven't had a chance to ride it yet as weather is not good here now.
