Hello all,
Without a long discussion on trans oil I know to you use GL-5 but should it be Dino oil only or can you use synthetic as well. Also, someone mentioned to me that add a GM manual trans additive along with the GL-5. Any thoughts will be appreciated. Thanks everyone! Steve |

Gear oil fight whoopie (IMG:style_emoticons/default/chair.gif)
914 Kid has it right. It's hard to find plain old GL5 Hypoid gear oil. I found some CarQuest brand sold by the gallon only. It's super cheap, but it works. You want NON limited slip. Stay away from synthetic and SWEPCO. Makes your trans spin way to fast for old syncros. I tried it in my car and (IMG:style_emoticons/default/barf.gif) couldn't get it out fast enough. |

But then way back in the day I didn't have any problem with Slick 50 either..... |

Probably more than one change to get all the Swepco cleaned out. I need to do another change myself. You have multiple cars, so try the worst shifting box you have. I wanted only the best for my car and so I bought the Swepco. It's hard to believe when you spent all that money it's got to be better. For a new modern trans, yes it is. For an old 914, no. |
