OK,
Anything but the simple things with me... I know..
First off, Aluminum driveshafts; Does having less rotational mass cut the parasitic power loss down enough to where I would want less strength where it counts?
Second off, I'm a bit worried about mine, getting a nice unusually strong vibration, verified driveshaft vibrations, above about 90 mph, in neutral, engine dropped back down to a stepped idle. Yes, spider gear and whole rear end is in great condition, I'm sure its the driveshaft.
Third, Dexron Mercon III ATF in my T56, is there a better idea? What would some of you guys recommend? My guess is the ATF is used because of tight tolerances?
Thinking about a new DS after replacing the stupid forward pinion seal that goes bad on the stupid 10 bolt...
Thanks everyone!
