The NV4500 uses 80w90...the other NV variants (e.g. NV5600, NV3500, etc.) use synchromesh. I ran synthetic 75w90 for over 250k miles in my dad's NV4500...it stated the gear oil part number right on the tag, while my NV5600 stated "Synchromesh" on its tag.

 

Point being, make sure what you are supposed to run...as far as I know, all NV4500s are a gear oil, not synchromesh.

Oh really? That's different...I thought all nv's were synchromesh. I stand corrected.

yes i know syntorque is different than syncromesh. i am willing to pay the 30$/l from my near by dealer to know i am running a quality oil. from what i have read the syntorque was designed specifically for the nv4500. i love my tranny and want to treat her right, it is not like the fluid is a frequent thing to change. so for the 120 in oil i will be a satisfied man.

No go to the dealer and give them your vin use what they recommend. Do not just throw something in there, transmissions are sensitive to fluids. Especially the brass syncro's.

 

I've already told you what to do for the tcase.

Merchant automotive oes have the pump rub kit but they dont seem to have the cast aluminium tailhousing just the magnesium, where i am hoping to upgrade to the aluminium, though i am slightly confused on which would be better for this application, from my reading the cast aluminium takes a bit more abuse, and less wear from rubbing but the magnesium disperses heat better and is lighter weight.

which would you go with? i like that merchant automotive has a complete kit with everything i am needing.

what are your thoughts on aluminium verses magnesium?

Same thing...you won't find an aluminum casing anyways unless it's billet. Which would be ungodly expensive.

 

Just do the pump rub kit and be done worrying.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
