If you have the BW44-44 TC, you should be fine with that one as long as the label on the bottle says pre-2016 44-44

I believe that is for the 2016 and newer 44-44s, Borgwarner changed the clutch packs and the fluid requirements changed, thats why FCA/Stellantis changed the fluid for 2016+.Has anyone has success with the ravenol transfer case fluid? View attachment 494536
Yessir, I've been running the Amsoil MVATF in my 44-44 for over 2 years now, 0 issuesDo you have the BW44-44 transfer case? And has that Amsoil product worked well with no problems?
Your RAM is a 2015, so you can use any Dexron III, TES-389 or TES-295 type fluid. The list is huge. Mobil 1 Synthetic ATF, Delvac 1 ATF, AMSOIL MV ATF, Red Line D4, Shell Spirax S6 295, and so on. The Ravenol BW44 is for 2016 and newer transfer cases that shipped with Mobilfluid LT from the factory.Do you have the BW44-44 transfer case? And has that Amsoil product worked well with no problems?
Not with my truck but when I had a Porsche Cayenne S Ravenol was 1 of the fluids of choice for many fluids on the Porsche forums. The transfer case fluid was especially well reviewed as the X-fer case was a weak link on these units.Has anyone has success with the ravenol transfer case fluid? View attachment 494536
I ordered several quarts of that a couple of days ago. This way I have more for the next time. Thanks for all that great information!Yessir, I've been running the Amsoil MVATF in my 44-44 for over 2 years now, 0 issues
Today I changed both front and rear differential fluids in my ‘15 ram 1500. Also the transfer case. I just passed 90,000 miles.
I got the rear tires up on rhino ramps. And I put the front of the car on 6 ton jack stands. I got the truck pretty level front to rear.
The original front differential fluid came out clear and looked pretty good. I used the redline 75W90 gear oil in that. It took about a quart and a half. Is that normal for the front differential?
By the way I let everything drain for a long time.
The next thing I did was the transfer case. again I let everything drain for at least an hour. That only took about a quart +4 ounces of the Amsoil (multi vehicle signature ATF) that normal?
Lastly the rear differential fluid looked very brownish. I let that one drain for a long time. That took about 2 1/2 quarts of the Redline 75w140. I was concerned about the brownish color of the original rear differential fluid. Is that normal for 90,000 miles?
Monday I’m going to do the transmission. I know that I have to get the transmission pan level which means to raise the rear wheels. I’m going to be replacing it with the PPE transmission pan.
Going forward I’m going to be changing these fluids regularly. Any advice on when I should be changing the differential fluids and the transfer case again? I plan on doing the transmission every 40,000 miles going forward. Unfortunately I bought into the “Dodge BS” about these ZF transmissions not needing fluid changes.
I still have the vehicle up on the ramps and jacks stands. I haven’t driven it yet because I plan on doing the transmission tomorrow.
Thanks again for all of the helpful advice. I posted pictures of the fluids that I used (thanks to the helpful advice here). Once again please let me know if the amount of fluids that were drained out is normal?
Thanks again!
If your truck has the 8 speed,you have a transmission thermostat. Search Caulk04's name for his 8 speed thermostat bypass“Important to get rid of your oil cooler thermostat if you have one. Otherwise I'd change oil sooner. I changed @ 35k miles and oil didn't appear or smell good. Did not get it tested, but I got rid of thermostat at same time.”
How do I find out if I have an oil cooler thermostat? We have towed a 5’ x 10’ enclosed trailer occasionally during the past 15,000 miles.

Good for you! Sounds like you did a thorough job with top quality lubricants.
I'll try to give you some perspective from an old engineer:
1) Yes, that's about the right amount for a front differential. Yes, it's not unusual to not see much change in the oil since this box isn't used much for most people. Frankly, the only concern (unless you're snow plowing regularly, or other similar loaded use) is moisture contamination thru the breather tube. This box can go 100k miles, 50k miles if you live in warm, coastal area, or 4 years.
2) Same applies to your transfer case.
3) Rear differential oil is different in that it is in constant use, and also takes variable loads - if you tow full time or are a contractor, the gears get heavily loaded and oxidize the oil faster, consume the EP additive faster, and wear the limited slip clutches faster (if equipped). All that adds up to oil changes at 50k if heavy use, 100k if light consumer use (empty truck). Again, no more than 100k miles or 4 years due to atmospheric moisture thru the vent tube. I use 75W-90 because I don't tow heavy, or often. If I towed a 5th wheel all summer or livestock trailer all year, I'd use 75W-140. Most differential gear oil comes with limited slip friction modifier additive. It's ok for non-LS axles except torsen all-gear, which are slower to engage due to LS additive. I have torsen gears, I use Mobil Delvac 1. Red Line & Mopar also offer non-LS gear oils. Amsoil does not (confirmed with their rep.).
4) ZF transmissions are very good, but ridiculous for maintenance. You are correct - they should have maintenance. I'd say app. the same intervals as the other gearboxes - 50k miles for heavy use, 100k miles for light use. Some guys have had some slippage using Red Line ATF and suggest Amsoil Multi Vehicle ATF instead. Important to get rid of your oil cooler thermostat if you have one. Otherwise I'd change oil sooner. I changed @ 35k miles and oil didn't appear or smell good. Did not get it tested, but I got rid of thermostat at same time.
