Everyone has their own opinion whats best and some make money on selling certain brands..

I use Redline in the rear and tranny... I bought it from Jegs. 75w90 in the diff.. already has the friction modifiers.. Use ATF D4 in the tranny. Has to be ATF and dexron III compatible if you want to use whats recommended by the manuafacturer.
I have been using redline oil for many years and find it to be excellent, I'm sure the other premium brands also work well..

u will need 4 quarts for the trans and 2 quarts for the diff

this one for the tranny??

I use Redline Shock Proof Gear oil in all my vetts. I have had great results. I also use it in my Mustang drag cars.

no 75w90 for the diff.. you need ATF for the tranny.. If you use redline, get the ATF D4

Sometimes the added viscosity of dino oils is better in the tranny and diff.

??? Not when I'm running 30 minute sessions at VIR. I want all the heat protection I can get. On a C5 the transaxel doesn't get much air flow and the exhaust pipes pass directly under it... this can make for a hot trans/dif.

Yes it is,but you can use redline 75/140 synthetic for the rear as DTE recomends.

It's a preference in feel, synthetics are the most durable.

Redline uses friction modifiers for their tranny and diff fluids.. like you implied.. too slipery is not good..
Synthetics are better at lubricating and keeping things clean.. they can also can handle more heat which is important in the C5 as the main components don't get much airflow..

Sorry for coming in a day late on this one, but for future reference for those that would like to use AMSOIL:

Tranny fluid (meets Dexron III standards):
AMSOIL ATF (Product code is ATF)
Takes just under four quarts

Diff fluid (meets GM standards and comes with friction modifier in it)
AMSOIL Severe Gear Extreme Pressure 75w90 (Product code is SVG)
Takes just under two quarts

FYI, I use both these in my Z06 which sees exclusive track use. You can order via the link posted above (thanks Brian), or the info in my signature.
