Fluids for HMMWV

[SgtJay88]

Hey all. I just purchased a 2000 M1045A2. Doing some of the basic stuff with a new vehicle, and a complete fluid and filter change is probably due. What fluids do yall use for everything? I have the TM specs but the main one I'm having trouble finding/choosing is transfer case fluid. Thanks!

Well that narrows it down, good job. ACDelco, Valvoline, AMS Oil, Fram, Mobil or what?

If you are doing the hubs I would open the inspection cover and try to clean out any sludge that has built up. I replaced the gear oil and shortly after had to do a seal. I drained the new gear oil and it was all discolored from the sludge on the bottom.

The brand makes absolutely no difference

Ok thanks, that's all I needed! Just making sure I dont use something someone else learned not to

I put GL-5 gear lube in the diffs and portals. Regular green antifreeze works fine and your best bet for engine oil is standard 15W40 diesel oil, its super cheap at the farm store.

Sold parts for 20 years. Fram is junk. Research and many articles comparing cut up filters. Fram is now mostly a consumer brand sold at Walmart, home depot etc.
Not a professional brand sold to mechanics. Don't think any major nationwide parts chain delivering to shops even sell it.

Purolator L34631 is a solid filter, there's also the ACDelco factory one PF1218 which fits both my 6.5 and 6.2

Here is an oil filter cross refernce I use for all my vehicles. Personally, I love the WIX series. 51060 for this truck...

Did i read this right? Dexron VI instead of Dexron III?

Apparently DEX VI is backwards compatible with II and III, meaning you can use VI instead, but not the other way around. But I will keep using DEX III if I can find it.

Dexron VI replaced Dexron II and III, and can be used in General Motors domestically built or import transmissions that specified Dexron II or Dexron III. Dexron VI is a low viscosity transmission fluid and should also be used with the full synthetic low viscosity transmission fluid.

thx... I was afraid I had missed something. And suspected the Dexron III vs. ATF+4 situation that arose at MOPAR at the turn of the millennium.

Here in the US, I know O'reilly's still sells dex 3 in gallons only I believe.

I get mine from Wally World... It says Dex III compatible, I hope that's is correct? Anyone else out there know more?
