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.

Below in my signature is a link to several pages of notes. I go over all of the answers to the questions asked, and the possible faults.
Short answer for oil, these boxes lasted 30+ years on neglect and dino oil. You really dont need to spend more and you will not get improvement. Simple GL5 80-90w is all the factory recommended and I use the cheap stuff. Synthetic tends to be too slippery and our boxes work on friction. Also, fancy oils tend to have fancy emulsifiers and detergent packages included with them. This is not necessary and can actually, in my opinion and experience, cause harm over time (read my notes for more details). As for noise abatement: IF your box is in good shape, just tired, you can substitute a qt of Lucas oil stabilizer. I use this for assembly lube on my builds because it is as thick as honey and stays on the bearings to assure that they are lubed from the first turn of the crank. This is the stuff they sell everywhere and has the cool little display with the gears showing the lube crawling up the gears v not doing so with the regular oil. Used in over a hundred builds and was actually a tip passed down to me from an experienced Porsche mechanic (which is why I was no hesitant to try it). It will get rid of high pitched whines due to wear over the decades. Also, keeps lube locked into the bearings which sit outside of the oil bath. Eventually, though, you will need to open and inspect bearings and R/P health. |
