sup guys,
iam changing my tranny oil and i didnt know which kind i should go with, my car is a 98, 5sp with 146000 mile on it so what do u guys think?

thanks.

 

How to change manual transmission fluid? Which fluid: GL-4 or GL-5? Best gear oil?

With Amsoil Series 2000 no longer available, it looks like Redline MT-90 is the recommended gear oil.

 

looks like Amsoil Series 2000 has been replaced with Amsoil SAE 80W-90 Synthetic Gear Lube

seems to meet the same requirements: http://www.amsoil.com/products/agl.htm

 

Why did they stop making it?

 

It's still in the Amsoil on line catalog

 

The new product, Severe Gear, is GL-5 rated, not GL-2 thru GL-5, and so is not recommended.

AMSOIL AGT is still available, which is apparently what many orgers use. It's an 80W-90 GL-4 gear oil. It's only available in gallons, so two gallons will be needed.

Another option is ALU, which is "Marine lower unit gear lube" but it's an 80W-90 GL-4 rated lube that can also be used in automotive applications specifying a GL-4 oil.

I'm not sure why AGR and AGL wouldn't work also. Both are rated "GL-2 through GL-5".

Sheesh, I just want some gear oil. It shouldn't be this complicated.

 

who says AGL wouldn't work? that's what amsoil recommends...

 

I have 26K Miles on my maxima, whats a good mileage to change transmission fluid? Or i should just wait till 50K and get another tranny? lol

 

The only products AMSOIL now offers for our 5-speed transmissions is AGT, available in gallons only, and ALU, "Marine lower unit" lube.

I could have this wrong though, so corrections are appreciated.

 

where did you pull that quote from?.... that's lousy news

 

Everything you state is correct :-)

 

AMSOIL has changed their line of gear oils effective 1 Oct. While remaining stocks of the previous formulations will be sold, the Series 2000 Gear oil will be replaced with a new formulation called "Severe Gear"...that product is GL-5 rated. The previous AGR (75w-90) has been replaced with a new "Long Life" line of lubes, and that too is GL-5 rated. AGL (80w-90) has also been reformulated and it too is now a GL-5 oil. To the best of my knowledge, AGT and ALU are the only GL-4 rated oils remaining.

 

It would seem, from reading the product info on AMSOIL's web site (www.amsoil.com), that AGT and ALU are the same product. ALU is available only in 8 oz. tubes and quarts, AGT is available only in 1 gallon bottles, 5 gallon pails, and 55 gallon drums. In various places on the web site, they refer to AGT/ALU.

If this is true, then a gallon of AGT plus a quart of ALU would be the cheapest way to go.

talkinghorse, can you confirm whether AGT and ALU are the exact same thing?

 

S15 SR20DET: If I were you, I will wait till the end of the year for DexronIII(H) to come out. The licenses for the major ATF producers expires for the GM DexronIII(G) spec that you see OTC today and the ATF meeting this new spec will greatly reduce shear, oxidation, reduce shudder etc, etc.

It is expected to be be carried by many shops early next year.

 

I've consulted with AMSOIL tech services on this very issue before, and they advised that the only difference in the two products is that the ALU contains additional amounts of water emulsifiers to protect marine lower stern units in the event water were to be injested. They also confirmed that ALU can in fact be used in GL-4 and MT-1 automotive applications, and the product is labeled as such. So yes, the least expensive way to go is with a gallon of AGT and a quart of ALU.
