Dextron is an ATF - Automatic Transmission Fluid, not for your manual.

Weird, cuz here is a pic of a manual T56 in a corvette.



but i think i found the answer,, the answer is if its an auto use the dexron VI from now on.

if its a manual you can use the Dexron III or the GM part number 88861800...
..DO NOT USE Dexron VI in your Manual transmission...

My silly '00 Mustang GT t-45 manual tranny also takes ATF. I recently filled with Mobil 1 Synthetic ATF, I believe it is Dexron III compliant.

Not true, it uses Dextron.

I used Redline ATF and am happy with it. You can get a whole kit from Redline that has all of the fluids in it.

Dextron III is no longer made. Dextron VI in your favorite brand is a good replacement. In fact you will notice an improvement in the way the trans shifts with this newer fluid.

I believe you are incorrect. Mobil shows their Mobil1 Syn ATF, which is dexron III, on their website as do other brands. Mobil1 also shows the dexron VI on the same list.

On Valvoline's site...Valvoline DEX/MERC ATF is III, Valvoline DEXRON VI ATF is VI.

there is a TSB saying, DO NOT USE Dexron VI in Manual Transmission... which this thread is about, cuz i have a manual..

88861800 is the only recommended fluid for Manuals now.

a sutible sub if P/N above is NOT available is Dex III Spec H...

I would HIGHLY recommed using ASMOIL "Torque Drive" synthetic ATF. It is a high quality Dex II based synthetic that is much better then any petrolium oil and will allow much longer changing invervals. The GM fluid is basically a regular Dex III fluid and it re-labeld as part # 88861800.

DO NOT ever use Dex VI in any manual trans application.

If you have any questions about the AMSOIL product, feel free to PM, email or call me. I am a dealer and will be happy to answer any lubricant related questions. I have switched all of our cars ( C6Z06, '05 GTO, '07 Trailblazer SS and '07 Chevy Z71 truck) over to AMSOIL in the engine, trans and diffs and I am very happy with the results. I can now go longer then I previously could on the invervals and the oil analysis comes back much better now then with regular oils or Mobil1 ever did.

If you want to order, you can just do it right off their website and pay the same prices as walking into a dealer. You can also sign up to be a preferred customer and receive all oils at a wholesale discount, shipped to your door.

The AMSOIL site is www.amsoil.com . All of the products are listed by category and easy to find. The recommended fluid for the M6 trans is here... http://www.amsoil.com/storefront/atd.aspx

for any order, please use referral # 1855896 and let me know if you need any questions answered.

There are other threads that cover this in more detail, but the bottomline - DEXRON III is no longer made. Anyone can call their product Dex III Dex 3, or any other name they so choose. GM licensed this name in years past. During those years, for someone to use the name Dexron III it required GM authorization and they had to meet the GM requirements. This is no longer the case. Anyone can now use the name and the name means nothing. Any of the lookalike fluids out there are closer to DEXRON VI in makeup than to Dexron III.

And tell them it's not an official link from GM.

Try TSB 04-07-30-037D at http://www.alldatadiy.com/ where you'll read:

"The content of this bulletin does not apply to manual transmissions or transfer cases. Any vehicle that previously required DEXRON®-III for a manual transmission or transfer case should now use P/N 88861800."

Or go to your local GM dealer and have them show you the TSB if you don't want to believe an overwhelming avalanche of proof...do a search in any search engine and you'll find millions of hits.
