I currently use Amsoil 2000 0w-30W Severe Duty motor oil...

I'm looking to change the trany fluids for a better lube. Which of the Amsoil trany fluids is best for our Z's... I'm looking for the best protection!

Should/might the dealer change out the trany with this new Amsoil product... It should meet and exceed GM's spec??

Any other product i should consider changing while there?

Correct. You should always replace fluids with those that meet or exceed the manufacturers specification requirements.

For the Tranny it must be ATF that exceeds Dexon III, Plus using a Synthetic is even better

I recommend AMSOIL:

ATFQT Amsoil Synthetic ATF

For the Diff I recommend:

SVGQT Amsoil Synthetic Extreme Pressure 75W-90 Gear Lube

(Meets or exceeds API GL-5, & GL-4)

ADABA Amsoil Slip Lock Differential Additive (4 oz)

G2039 Hand Pump is also helpful.

Both fluids are excellent for street and track use.

I ended up with Severe Gear 75w90 for the Differential. I am fairly certain that the Amsoil Severe Gear already contains the additive, so I wouldnt bother putting it in unless you fail the figure 8 test..

BTW, amsoil has a great application guide on their site: http://www.amsoil.com/scripts/runisa.dll?amsoiloaf:index

AMSOIL Synthetic Extreme Pressure 75W-90 Gear Lube does NOT have the required Differential Friction Modifier in it for Locking, Limited Slip and Positraction Diffs that GM recommends.

I strongly recommend that it be used with the Gear Lube.

DJWORM, to clarify, do you know if Amsoil Severe Gear also does NOT have the additive?

Sorry, I may have confused you. We were talking about the same product.

AMSOIL Synthetic Severe Extreme Pressure 75W-90 Gear Lube does NOT have the GM required Friction Modifier in it.
