Hey all....maybe I am just hyper sensitive but I think I am hearing my transmission while I drive.....maybe just a little too much. Could just be normal. Anyone know of a super quieting tranny oil? I think I am using Stalube 85-90 or something like that. Thank you very much.

Keep in mind that the oils you buy now are not considering the intricacies of a 40yo Porsche transmission when making blanket statements. You will see that GL5 is also not recommended for transmissions with "yellow metal" in them, which ours clearly are, and GL4 is the preferred. The GL refers to the detergent and other additive package in there. The GL5 can stain the yellow metals of the shift forks and bearing housings, but this is not an issue in operation and the engineers at Porsche were well aware of this. As long as you stick to the weight, GL5, and no funny additives, you will be fine. It is when people try to outsmart the engineers and use really slippery stuff that their boxes get destroyed. I had one recently and I swear he used 10w as it was like water, clear, and smelled like fork oil. His box would not select a gear and this was why. |

Thank you very much Dr. Evil....I am going to put in one quart 80-90 and then the quart of Lucas, then top off with more oil. Does that sound right? I was going to flush the tranny with starting fluid or something that evaporates fast just to get a fresh start.....you ok with that idea? Thank you again, gg |
