Question regarding what lube for transmission?.....

[MSeriesRebuild]

I'm not going to argue this with anyone Charles. I read on another forum about the 90 weight GL1 Gear Oil, and I brought the subject up for discussion because I haven't read anything about it here. I'm using Royal Purple 50 weight in my truck and I'm not looking for any cheap alternatives.

You have made a wise choice with a high quality 50 weight.

I see amsoil 50wt is only avail in a 5 gal pail, and royal purple max gear does not come in a 50weight?

Did you check out the Lucas Synthetic 50 wt? I'm using it in my NP435 that I'm running, nice fluid and compatible with the box's materials.

Royal Purple max gear is not the correct oil. If you are going to run Purple, use their 50 weight engine oil.

Oils blended for trans use are the best products to use. 5 gallons is not that much to have on hand; by the time you fill the trans and transfer and have some available for top off and the next time you need to change it. It will save $$ also, I guarantee the next time you buy any product, there will have been a cost increase.

no I havent, maybe I will. that 5 gal of amsoil is like 250 bucks and I might drive the thing 200 miles a year so 5 gal is alot!

Any high end oil is going to run in the same retail price range. The fact that you only drive a couple of hundred miles a year really is irrelevant, a sparsely driven vehicle demands a higher quality product than a fequently driven one because of condensation issues. The oil needs to cling to vital parts during idle periods, lesser quality oils have no clinging additives at all. Rust build up on internal parts due to condensation will be the result. There is no substitute for high quality lubricants, it's simple, you can pay a little more for high quality products now, or a lot more for costly repairs later.

If you are considering Amsoil products; you can become a prefered customer, and buy any of their products at dealer cost pricing, much less than retail. All it takes is a phone call to become a prefered customer. You will get one of the best products on the market today at a very reasonable cost. This is the BEST deal out there for high quality lubricants.

Thanks, Carter!

I didn't see that post by Charles last July. Very useful information. It certainly has saved me from making a mistake on winch lubes.

So, what should go in the winch and steering box?

Thanks, again!

Worm Gear Lube, ISO 460 is the prefered product.

Thanks, Charles!

Any particular product name?

The worm gear lube we have on hand now is still some Royal Purple product we are depleting before changing to Amsoil. Worm gear lube can be purchased at any industial lubricant sales outlet. Many different brands offer a product that meets the spec. The ISO 460 is good for moderate temps, both cold and hot. If you are in an area where temps are warmer than average in the US, you may want to consider ISO 680 which is a heavier grade.

Thanks, Charles!

I appreciate the benefit of your knowledge and experience.

Thanks for the recommendations.

Sorry for bringing up an old thread but it was a good one and I had some questions.

Going to flush the transmission and T-case. They're both shifting fine, but whining a little bit at speeds above 40-45, so want to make sure they get a full flush and what not. My dilemma is this. No amsoil dealers anywhere close to where I live so that is out, same with synergyn. I have an abundant supply of SAE50 Royal Purple, but responses indicated it isn't as good as it used to be. Wanted to confirm this, and see if there were any other recommended oils available through Napa, Carquest, Advance etc.

Also, SAE 30, 40, 50. This truck will be driven in winter in temps approaching 0*F so do I step down to 40 or 30? Any multiweight options out there for the colder weather driving conditions? 15w40 etc?

Thanks

I'd use the SAE 30 at 0*F. You may need to change up a grade if it is significantly warmer during summer months.

Getting Amsoil products is easy, you can either call it in or order on amsoil.com, it will ship out of the warehouse nearest to you. Ours ships out of Richmond, VA.

Be careful flushing; take care to get every bit of flushing fluid out of the unit before refilling. If flushing fluid is left behind, that can dilute your new oil causing major issues. This is especially true if you have a PTO that has no drain plug.

[tbone1004]

Sounds good. Significantly warmer up here is about two weeks a year in the 90's and mid-hi 70's for a few months surrounding that so would a 40wt be better overall compromise?

No PTO so that's not a problem.
Thanks for the suggestion on getting it shipped, figured you guys were getting it from the dealer in Charlotte, but good to know it ships.

If running at 0*F, you need to run 30. No warmer than what you say, 30 will be fine year round.

Small or run of the mill dealers don't stock anything but over the counter products in quart bottles. We buy in bulk, much cheaper, ours is delivered truck freight, also cheaper.
