[396 Hawk]

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?

I have d4 in my tranny and one of the redline fluids in my rear (synthetic 75/90 rings a bell?).

Now, i do remember reading something on one of the ls1 forums that synthetic tranny fluid is a bad idea (for the t56, or at least the ls1 t56 if there is a difference) had something to do with having paper liners for the syncros or some other part, and the synthetics would eat it apart after time. I don't know of any truth to that, but i figured its worth mentioning here.

personally my gearbox is probably fine, but now that i'm paranoid, it does gring going into 5th when cold, and its been tough to get into 1st from a stop unless i double clutch sometimes. I have nearly 80kmiles, gone through 2 clutches, and my driving style is probably considered spirited. don't konw about the owner that put the first 19kmiles on her though....

anyone else heard about synthetics being a no-no for the t56? I think i remember something like the viper t56 is immune to this problem, and possibly the c5 t56, since they didnt use the cheaper paper lining?
