NV5600 Lubricant?
Would AmsOil 5w-30 be a good oil to put in a NV5600 6-speed? My friend said Amsoil 75w-90 but that doesn't seem right at all.
For an application that calls for Dexron II; Would Dexron III be okay to use?

Re:NV5600 Lubricant?
On the Dexron II-III; depends on the application. If you're talking about a transfer case, for example -- you're fine. If you're talking about an automatic transmission -- sometimes yes, sometimes no. The two ATF's have somewhat different characteristics and in certain applications it can make a difference.
On the NV5600 oil -- 75w-90 is NOT a good way to go, and neither is the 5w-30 -- Amsoil or not. 75w-90 is usually a GL-5 rated oil, and will hammer your synchros and yellow metal -- you'll get maybe 50,000 miles out of the transmission before you'll have to rebuild. On the other hand, 5w-30 will not be able to handle the intense shock loads and shear values of the transmission gears -- especially in the NV5600, which pulls heavy loads behind a high-torque engine. You'll end up chipping and cracking gear teeth.
Go with Redline MTL. It's a low-sulphur, GL-4 rated oil with friction coefficient additives for the synchros, and is the best compromise between saving your yellow metal and saving your gears. Royal Purple is also good, but I prefer the Redline product, largely because I've experienced a quantifiable difference in shifting and heat build-up.

Re:NV5600 Lubricant?
Yeah. The Dexron II/III question was for my 241HD-PTO transfer case. Is Redline MTL a widely sold product that most Auto parts store prolly carry?
I went to the Redline Website and they stated this
"Red Line MTL is classified as a 70W80 gear lubricant "
Would this not be the same as using Amsoil 75w-90?

The Series 3000 5W-30 HDD is what Amsoil recommends for the NV5600's...Hope this helps.
Gear Poet, 106K on my NV4500 with GL5 and no probelms...Not even a fifth gear nut. Amsoil's GL5 has a buffer in it that takes care of the yellow metal problem.

Re:NV5600 Lubricant?
Both DC and New Venture recommend against using any 5w-30 oil in the NV5600. So do most of the major rebuilders and kit-swapper manufacturers. Redline MTL is an "equivalent" lubricant to both 70w-80 and 5w-30 -- which means that it can function as a replacement for either in manual transmission conditions, but has additional properties that both don't have. DC's and New Venture's recommendations for the NV5600 are different than for the NV4500 -- DC's lubricant is a different part number in my manual and in my dealer's books. The recommended lubricant has a low viscosity, is synthetic, and has formulated properties of both a GL-5 and a synchro-specific fluid. <br><br>Redline is usually not sold by local autoparts chains -- it's expensive. You can find it on the web -- Summit carries it, but I use Al Smith's outfit in Baltimore. <br><br>Many people swear by Amsoil products, ratings, and recommendations. Many people don't. The GL-5 yellow metal buffer solution has been tried before by Pennzoil and Mobil, but my information is that the additives tend to break down after a relatively short period. Ultimately the choice is yours --I suppose, with a lot of luck, there are manual transmissions that will run tens of thousands of miles on mineral oil or cod liver oil. <br><br>GP

I installed the Amsoil 5W-30 HDD in my NV5600 when I had 5200 miles on the truck. Now have over 48K miles many pulling my 12K lb. 5er. Trans still shifts like new. This was the lube recommended by Amsoil Tech. Services. I checked the product data sheets for both lubes and properties were almost identical.

I would not use the Amsoil 5/30 engine oil in the NV5600.<br><br>The viscosity index of the Amsoil is 175<br>The same for the Texaco is 208.<br><br>The high viscosity index will lubricate the NV5600 from 40 below zero to plus 300 degrees and still remain viscosity stable. It also contains a fluidity modifier.<br><br>I like the Redline too.<br><br>Don~<br>

I just installed a BD short throw shifter and genos **** for my BD break and figured it was a good time to change the fluid. My service manual calls for "mopar manual transmission lubricant" since I had to go in to pick up a set of tow hooks any way I picked up the fluid at the dealership. They said when their techs change the fluid it only takes 3 qts. I said I wanted 4, when I go to the cashier she tells me its $20.99 a qt - full synthetic. After draining and adding all 4 qts it came out of the fill hole. Project completed. Then my buddie reads the back and it says it is "formulated for the nv4500." Is this the wrong fluid and do I ned to get knee deep in the dealeership? Should I add an extra qt totaling 5?
