I got a ws6 with 30k miles anyways im doing the fluid change all the oils. I read the owners manual and it showing for the manual transmission i need to get the additives and for the rear end. Where can i purchase these additives. Also if i use AMSOIL or Mobil 1 or Royal Purple do i need these additives??? Which brand would you prefer thanks guys!!!
I am not sure about the m6 but for the rear end most companies have the limited slip additive in it already, it should say on the bottle.
I am not sure about the manual transmission as well, but the additive for the rear end you can get it at the dealer it cost like 10-12 dollars.
Which dealership? also what brand would you recommend thanks!
Any Gm dealer should have it. as far as rear end oil I used the Mobil1 75w-90 you'll need two quarts(i think each bottle is a quart).
Amsoil worth it?
You can buy limited slip additive at most parts stores. Even with a Torsen rear (which your car should have) the manufacturer recommended the additive to combat what has been described as a "rusty screw" noise. However, if you utilize a synthetic gear lube, you can probably forgo the additive without any issues. (Someone want to verify whether or not 2000 model year cars came with a Torsen differential?)
Fluids? Name brand oils including Mobil 1, Penzoil Platinum, and Amsoil are all good. Royal Purple is generally not recommended on this Board based upon test results (we have a thread somewhere). Also, go with a quality oil filter - the newest high end Fram filter is actually a good one to get, as are Wix, Napa Gold (same as Wix), Mobil 1 and K&N.
The only RP product I use is their rear end fluid. It is really high quality stuff, the same if not better than Valvoline that I previously used. That said I am going to switch everything to Amsoil especially since I get it at a discount.Quote:

Ive heard that the Amsoil is pretty good for the transmission, i think im going to go AMSOIL in everything.Quote:

I have heard from many transmission people that synthetic oils should NOT be used in T-56 transmissions. That is just what I heard. I have Dex IV in mine and it works great.Quote:

I used that the first time without the GM additive and 10,000 miles later I notice some noise on the back. One of my bearings went out. It could have been that the bearing was getting ready to go bad before though.Quote:

Is this true or is it ok because on amsoil website it shows it's Dezrin iii approved... Please let me know thanks!
Jeff, I'm just getting around to changing out the fluid in my '02 T-56. I didn't get on this site first and just went to Advanced Auto and they sold me Castrol transmax Dexron VI Prem. synthetic blend Automatic trans fluid. It says it exceeds Dexron III H requirements and for use in Gen. Motors Vehecles. What is the 'H' requirement? I haven't put it in yet and I'm glad b/c after doing some reading, I'm not sure I have the right stuff. What do you recommend??
From what I could findQuote:

So,,,,,, can I use the Dexron VI or should use Dexron III or is something better out there for my 02 T-56. I'm a little confused and don't want to use the wrong stuff.
I have Castrol Dexron VI Synthetic Blend in our car right now -- no issues. It is approved for use in vehicles calling for the older spec fluid.
Thanks for getting back to me,,, Just from what I've been seeing on here I'm shying away from synthetic or a blend of it. I had already returned the VI and got the Castrol Hi milage ATF before you got back to me. I just completed the job. There's one thing people neglect to mention... I discovered you need a pump to get the fluid into the trans! I was already up the ramps and had to go back to the store. Live and learn. Also, you don't need to buy 5 qts b/c it takes 4.1 quarts.. at least .1 quarts stays in and just 4 is plenty. Just food for thought for any other 1st timers like me .Quote:
