I don't think it's ever been resolved. To me, it comes down to this: The conventional D3 simply shifted the best in my tranny. I'm happily using synthetic in my engine and diff, but if it wasn't for the bearing problem (which was caused by a bad pressure in about an hour of driving, NOT an oil-related failure) I would switch back to the Castrol D3 in the tranny and never look back. Whenever I get it fixed, I WILL switch back.

newbie Group: Members Posts: 30 Joined: 4-October 04 From: Wilmington, DE Member No.: 478	Even though I don't track my Hawk (for now), I figured I would ask some of you race guys what you use in the tranny (M6) and rear (4.10 10-bolt) of your cars. I'm going to change all of my fluids in the next week or so and have used Redline in the past with pretty good results but have been considering Royal Purple. Any suggestions?
