American Muscle doesn't sell Signature Series, only XL....and they also do not sell MTG.

Amsoil XL is their cheaper true synthetic/hydrocracked synthetic blend.

It's not as good as Amsoil's Signature Series (100% true synthetic).

Anyone can buy Amsoil @ dealer cost, and you can even buy their Signature Series for only $7.85 per quart by signing up as a preferred customer.

I don't think they even make a signature series that anyone with a gt500 would want either. At least I did not see anything for 5w50 or 10w40.

I know they recommend atf for the tr6060.

Redlines 5w50 has shown great results in the various analysis too.

I wouldn't be too sure about that.

I have proven thousands of miles ago, using the 170* thermostat and Amsoil ATM 10W-30 (Signature Series) is the best lubricant I have tested to date. Oil pressure is never lower than 20-23 PSI (100* Ambient) and still has boat loads of pressure above 2,000 rpm.

On the other hand, Amsoil 10W-40 AMO ZDDP formulation is their true synthetic 10W-40. The reason why it isn't in the Signature Series family is because it has a different anti-wear additive package.

10W-40 uses high ZDDP as the primary anti-wear additive.

Signature Series uses lower levels of ZDDP, but boost the anti-wear package with moly and boron to compensate.

Both are great lubricants for the GT500 5.4L engine for a street or drag racing car using the 170* stat, more preference on 10W-30 due to better oil pressure. I give greater preference to the 10W-40 when the stock 192* stat is being used.

For a road racing car, despite what thermostat is being used, I prefer the use of 10W-40. The car is going to get the oil HOT on extended racing sessions. The higher viscosity and HT/HS will be required.

Red Line 5W-50 has shown great anti-wear metals in the UOAs, but has had terrible results in longevity of TBN, the engine is more sluggish on cold starts ups, and users experience lower efficiency (i.e. mpg).

In the ATF department, Amsoil ATF kicks booty in the T6060, T3650, and T56. I've tried all the other great true synthetic ATFs, and the only two that came close were Red Line D4 and Mobil 1 syn ATF, however that was the older Mobil formulation. They have since moved on to their new line of VISOM base stocks, and now are refined petroleum, not a true synthetic.

So ive completed my fluid swap, I think I got more on the ground than in the transmission but it seems to be fine , so as for the changes!!! My trans was still warm and I went for a drive , there was a difference in selecting the gears 1,2,R specificly they were butter smoothe . So after sitting all night in the garage 45degrees I pull out this morning and it feels just as notchy as it ever has, first few shift were ugly as compaired to the night before. After a few miles it feels alright , being 35 outside I doubt it ever got warm on the 7 mile ride to work, I think the fluid swap has made a difference but best results will be at operating temp.

Did anyone else when using the hand pump have fluid constantly spitting back out of the hole? This is the reason im hoping I have the propper fluid level in there, I know I used a roll of paper towels cleaning up . Also is there no good way to check fluid level besides knowing how much you put in? If you were not sure would it be ok to just fill it to the fill plug level?

You don't want to fill it up to the hole if you've got an MT-82. That will take much more than what's recommended.

I will use a clean catch container in these situations. The trans has to be cleaned up really well and you also need a good container that's either never been used, or, is super clean. You catch any that you spill and pour it back into a bottle. Then you know how much you got into the trans.

Personally, I didn't spill more than a few drops while doing mine. The hose going into the fill hole needs to leave some room around it for air to escape. This way, you don't get the pressure bubbles that force fluid back out.

To clarify, you had stock OEM pre-TSB fluid in your transmission before you installed Amsoil MTG.

It shifts better at operating temperature than OEM did, and at cold start ups, MTG was just as notchy as OEM. The difference is, MTG seems to begin shifting, warms up faster, than OEM did.

This is how I interpreted your post. Am I incorrect on anything?

Has anyone changed from the pre-TSB fluid to MTG and noticed a decrease in whine in 1-4?

From what I understand the 1-4 whine is a lash problem in the intermediate shaft (which is why it doesn't happen in 5th, since that's 1:1). I'm not opposed to masking it using a superior lubricant, but in this case it seems like using a software approach to fixing a hardware problem.

My 2011 has 2221 miles on it, I'll change to MTG in the spring when I get it out of storage and over to my brother's hoist. Just trying to set my expectations...

sorry for the confusion, posting from a phone is not the way to do it!! When the transmission was warm last night it shifted great, This morning 45 degrees in my garage , i left for work and it was notchy as hell, first and second gear were harsh engagement. with a little nibbel into third, a few miles down the road and it was feeling about normal, maybe a little better having given it a litttle time to warm up (highway 70 +). The fluid that was in my car was the stock fluid non tsb, but mine is a 2012 so im not sure what it had in it. im gonna go pick up another quart and drain/refill with a better hand pump tonight , cause im not sure i got the correct amount in there due to all the spilled fluid and horrible hand pump from oriellys, I assume if it were too low it would whine or something

Factory fill is 2.75 quarts in the MT-82.

Assuming no fluid was spilled, you should have 1/4 quart left over after filling the transmission.

Answer me this. The Amsoil MTG is the same weight as the QS fluid, so why would I see improved cold shifting when the MTL i'm using now is notchy until it gets warm? The MTL is super smooth during the summer, will I see the same with MTG? I don't want to have the same notchy shifting I had with the factory fill. I'm just concerned since the MTG is a heavier weight than MTL.
What makes the MTG better than the MTL, other than it's the correct factory spec?
Just curious, that's all.

I was thinking the same thing concerning the cold shift problem. I don't see the MTG fixing this issue.
