Axle and transfer case service

[Michaelsloft]

Since your well versed in transfer case operation and repair please tell me what internals in a BW 44 such as are installed in our trucks require special lubricants. I eagerly awaite your response.

I saw on TV and read on the internet that the weather has been miserable in Rhode Island so far this year.....

You're seemingly missing the point here.

 

[jhenderson]

Don’t believe I did. You told me not to assume anything. Since the only assumption I made was you’d never been inside a transfer case, you obviously were referring to that in particular. Now about those internals you’re so familiar with?

Don’t forget to write again when you’ve got something relevant to say.

You're serious.....? This is embarrassing

You just confirmed the Weather/News on TV and Internet are sometimes not fake and often accurate.....Thank you Sir.

What? That I expect those that criticize me to be able to back it up? Or the fact that you can’t?

If you think the weather reports are often accurate it explains a great deal.

You are still NOT getting the point.

One of us isn’t. That would be the one with no info. relevant to the thread. Ring any bells?

I will tell you this, I replaced the transfer case fluid in my dads truck with the special BW44 fluid. It is blue colored and slightly thicker than ATF+4. If it were my truck...I’d use the specified fluid as it’s clearly not run of the mill atf. My humble opinion only.

The original Transfer case fluid from the factory I drained out looked just like Red ATF+4 . That's what I put back in. Guess what?, my transfer case hasn't exploded yet, and I'm in 4WD almost daily.

MerCruiser years back was having some issues with their Bravo series outdrive's clutch system not lasting. They had copied Volvo Penta's system as soon as the patent ran out only they chose to use a different metal for the clutchcone asy to save money. They had been using 90 wt gear lube in everything up until that point. Not wanting to redesign the clutch they started to look into additives for the lube oil. In the end they came up with their own blend that not only solved their clutch failure issue but also made gear sets last almost double their life. Proven in MerCruiser's own test cells and on Lake X in Fla.
My point here is while I'm sure that the internal parts on our BW transfer cases are very much the same as the NP units just by chance BW like MerCruiser has come up with a Gear lube that allows the unit to last longer. For the 2 qts needed I think it it's worth the cost. Think about it the truck you bought cost up words of $50-$80K you are going to cheap out on the products that make it work day in and day out.

At the big Truck National Truck events, You will fine test labs, Take Your ATF+4, and 68089195AA BORGWARNER 44 fluid Pay the small fee and see for Yourself.



N68089195AA BORGWARNER not recommended for use in other applications. FCA Does NOT want you using this in other uses? Hmmm Its either not that good or its $? or agreement? FCA makes $ off ATF+4.

The difference being, Merc built the unit, developed the lube and then made the recommendation( or requirement for warranty) Borg Warner built our transfer cases but flat out refuses to even recommend a particular fluid. Now look at Aisin. They build our trans and put a sticker right on the transmission that gives the fluid requirements. They don’t require Mopar fluid, but a fluid that meets JWS 3309 specs. FCA does the same with their transmissions, requiring atf+4. Any required fluid has a spec to meet, and it’s listed in API specs that can then be met and produced under licensing agreements. They recommend Mopar, but any ATF+4 meets warranty requirements.

TDR1 members Take there lube and Fuel Very Seriously..... How many shops used Universal ATF that their supplier provided? that owners experience shift shutter all the while the Shops were claiming its universal so its OK. The 47/-RE from -19XX-2002 was plagued with Problems UNTIL Chrysler develop ATF+4
