Normal, haven't had the time to put into it, like the old days, kind of miss it, we had some good times, with the "Amsoil wars"

I am glad they came up with a 4500 lube, I was busy trying to corner the market on the remainder of the Blue 2000 series,I could locate that they discontinued. :{ I loved that stuff, saved me some money in parts. I saved all my old stuff, I was going to filter it and put it back in!!



I would, however, use Redline over Royal Purple or the factory slop. :-laf

Redline MTL synthetic here specifically designed for Manual transmissions... ... , ]



Yes, and let me finish that sentence for you Justin... ... "Popular in many BMW transmissions and in most Honda and Acura transaxle applications. "



ROTFLMAO!!!



Are you sure you have a heavy duty truck lube in there? Better double check!!

We've covered this before... The film strength's of synthetics make more of a difference than viscosity.



Hey I remember that little conversation now Rman, just didn't remember who I had it with ;)



Not trying to tell people what to use in their transmission, just pointing out something I see as a potential caution to those who may not be aware. Given a choice between RP Synchromax and Amsoil 5W30 for my NV5600 I'd go with the RP, since it's designed as a transmission lube like you say.

easy there trigger, I was responding to someone who had specifically asked about RP. I could really give a crap less what ANYONE runs in ANYTHING they drive. Put peanut oil in there I don't care. Just trying to help someone out...
 
I will be loking forward to seein the new lube come available. I am ready to pull the redline out and replace it. Was planning on running the Series 3000, but this new stuff may be the ticket!

Film strength and Viscosity do correlate, but in every book on oils I have read, and all the schools I have attended on oils, "Viscosity is the single most imoprtant property of lubricating oil"! If the oil is "Shear stable", then it has better film strength.

I think he's referring to the fact that for quite some time they said just use our engine oil... . it'll work just fine. Could that have been a rub your back tactic while we develop this new oil? The primary reason I went with RP synchromax was this. Why put an oil designed for engine conditions in a transmission. It's not hard to see lubrication requirements are far different in a transmission than an engine. I'm not questioning the quality of amsoil, I've been a user for many years. I just question them saying yeah sure use this oil... . then a couple years later changing their mind and saying, wait use THIS one now... are they going to put a label that says use either? If it were OK before... is it OK now?
Just to ease your mind if I can, the engine oil that Amsoil was recommending for use in the NV-5600 transmission prior to this newer lube, has more additives in it than is needed, as this was originally designed for engine usage. The newer 5W-30 (MTF) Manual Transmission Fluid does not have any of the engine oil additives that would be needed for engine use. Therfore, this is why Amsoil says the newer (MTF) MANUAL TRANSMISSION FLUID, 5W-30 is NOT TO BE USED IN ENGINES!



As far as engine oils being used in Manual Transmissions, most engine oils will meet a GL-1 requirement for use in Manual Transmissions. If you think this is funny, the Getrag G-56 transmission uses a ATF+4 lube, which is designed for Automatic Transmissions.

Wayne, I can't believe you got this info out so fast. You must have been typing on the flight home. It looks like you weren't sleeping during that afternoons forum.



As what's been stated earlier, Amsoil has products that will meet requirements for many applications. I believe they saw a market that wasn't being utilized. Even though our products can be used in the NV 4500, and NV 5600 transmissions, not all of you are using them because of various reasons. Now we've put together a lubricant for a specific application, and have listed part numbers that they replace. You've voiced concerns, and we've acted accordingly.

Wayne, wouldn't the transmission lube also contain a small amount of friction modifier to aid synchronizer function? You wouldn't want that in your engine if that's the case.



I would think the environment of an engine and transmission would be much different from each other. An engine would place high-speed but low impact/shear stresses on the oil, the transmission just the opposite.

Me, too. And since A-word tried to get me to use engine oil in a transmission, they lost me for a good while. WTH? Who in their right mind would use motor oil in a transmission? Stir, stir... . :p :-{}

Just to set the record straight, the following was taken directly from the API Service Classifications and was assembled for a "Service Classification system which assists in the selection of an appropriate lubricant for a general application. The number associated with the service classification typically denotes the level of application severity, and the OEM's determine what GL rating should be used. GL=Gear Lube.



GL-1 products Do not contain or require extreme pressure (EP) additives, and are Engine oils. They are typically used in applications in which EP additives are not required. They may also be recommended in equipment containing corrosive sensitive components such as copper, brass and bronze. A typical application for a GL-1 engine oil would be a manual transmission in a class 8 truck!



GL-2 Industrial Gear oils.



GL-3 Manual Transmissions, spiral bevel final drives.



GL-4 Manual Transmissions, Spiral bevel and hypoid gears in "Moderate" service. 50% additive treat level of a GL-5.



GL-5 Moderate a severe service in hypoid and other types of gears, may also be used in Manual transmissions.



MT-1 refers to the ability of a lubricant containing EP additives to function in elevated temperature application without producing corrosive by-products.



GL-2 thru GL-3 have moderate EP additives.



GL-4 thru GL-5 have high EP additives.



Typically EP additives are Sulfur and phosphorous containing compounds as well as Chlorinated compounds. The disadvantage of such additives is that they can deteriorate at elevated temperatures, and are generally not recommended for equipment comntaining sensitive components unless the lubricant also meets MT-1 requirements.

No Vaughn, the new MTF does not contain any friction modifiers! Niether does the HDD 5W-30 engine oil.

Is the MTF on the market today? Where does one find local dealer in NCal?
Yes, you can now order the MTF from Amsoil 1-800-956-5695 M-F 7 am to 5 pm Central time. It will be shipped directly to the address you provide. Stock # for 12 Qts. (1 Case) is:MTF-01. Stock # for individual Quarts is: MTF-QT I just ordered some my self.

I was planning on using the Penzoil Syncromesh. Not because I don't like Amsoil, in fact, I'm a dealer. But, I didn't feel Amsoil had a product that would be completely compatible. Apparently I wasn't alone.



Now, I'm interested!



Has anybody tried this in their truck yet (how smooth does it shift)?



How does the price compare to the Penzoil, which I have plenty of comfort with?
