I guess I have to ask the stupid question here. Are the tranny oil, and the primary oil one and the same? I can find no mention of separate trans oil. Try not to make too much fun of me. |

Yup, there's shared lubricant in the gearcase and the primary. Just like a Sportster. Sport trans fluid no longer available, many use synthetic 20W50. Petroleum oil will eat your stator. |

Petroleum oil will eat your stator. It's not "petroleum oil" that causes the problem. GL-5 gear oil (75W-90 or similar), whether synthetic or conventional, will eat your stator. DAMHIK. Sport Trans is no longer available from HD, but Formula + is. It's factory fill on 2006-up XB's, but seems to work well in tubers too. |

Formula+ is a good choice as it has good additives for transmissions (that can't be put in engine oil) but won't eat stator insulation. There are plenty of good gear oil choices, and plenty of good non stator eating choices, but we don't have much good data on which oils are both. We know the HD Formula+ oil is one. |

After having a throwout bearing go bad with syn3 in the trans, my HD/Buell certified mechanic that is self employed recommended Formula+ in the trans and Syn3 in the bag. He said bearing issues like that were not that uncommon when using synthetic engine oil in the trans. I switched to Formula+ and haven't had an issue yet. Use it in my S2 and S3. |

I use Formula+ in both my S1W and S2 in the trans. |

I use "Drag Specialties Gear and Crankcase Oil for Sportsters". It's specifically made just for thus purpose. A lot of shops won't carry it though because they have to order it by the case. I got mine from A&M Cycle when I was in Amarillo and I know we have a case or so here at the shop. (Message edited by Phelan on November 30, 2014) |

My nephew told me to not put anything in my trans/chaincase but this stuff. He won't use anything at his shop but this. It's about 8 bucks a quart. That seems pretty cheap compared to what it could cost for using something that would hose your transmission...
