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.

Sure the good doctor is right as he is referring to the 914 trans which he must know' better than anybody,so whats the secret to Swepco ? which the 911 guys all say improves shifting ,etc in those transmissions,no one seems to mention use in the 914 box that I thought was rather similar in design (IMG:style_emoticons/default/confused24.gif) .
Oil samples can't always be trusted ,last large vessel I ran had a massive gearbox failure due to worn out thrust bearing ,a recent oil sample showed no elevated levels of the bearing material in the oil,end result was a 6 month layup and around 1 million to rebuild it. |

Our guys have rebuilt dozens of 915 boxes and only use the GL4 80-90 dino oil. |

There is no secret to Swepco, I've run it and it's a good oil just super expensive for anything but race cars. @mepstein have you tried Motul? |
