Need to get opinions on the old style discontinued semi-synthetic transmission fluid from HD. Have a chance to buy some on close out from the local dealer.
Should I use it in my 04 Road King or go with a full synthetic like Mobil one or Spectro. Red Line not available locally so I'm not going there. Been using Mobil one 20w50 but want to switch to a true gear lube.
Any help would be appreciated.
