Old Tee,

What gear lube are you using in your 915 transaxle, and how recently was it changed. Porsche was recommending that the gear oil be changed at every engine oil change back in the '70s. What complaints do you have about your SC's 915?

If your brother-in-law's suggestion was to use heavier gear oil, or along those lines, I suggest flushing the existing gear oil with Valvoline SAE 85W-140 gear oil. If that improves shifting quality, then change it again within 500 miles with the same, or change to Swepco 212.
