Transfer case lubricant

[d90boy]

What is the best lube to use in the transfer case? In the past there were syncronizers in the case but with the permanantly turning front driveshaft I don't think there are syncros in the case anymore. There must be a better alternative to ATF for use in these transfer boxes. Any ideas?

Synthetic ATF maybe??

I use 5-30 synthetic MOTOR OIL in my '01. 5. It is about the same viscosity as ATF but lubes better.

After reading this thread I felt that I should add my experience. .



I was able to purchase a 5 gal pail of lube for the transmission in the GL4 spec in 100% synthetic oil from our local Castrol Dist.



I was also able to purchase a 5 gal pail of lube for the rear end in the GL5 spec in 100% synthetic oil from the same distributor...



He distributes the ATF - 4 oil for the transfer case but can't sell it to me as it's a private blended oil and can only be sold to DC dealers... . He has nothing on the shelf that will meet the specs of that private labeled oil..... until a few months ago he couldn't sell me the GL4 or GL5 either... ... He says it will be a while before he will have either the ATF - 4 for sale or something on the shelf in a different product that meets the same spec... .



They offer more than one brand of oil and I can't see where the ATF - 4 is available yet..... Since he only sells oil and I felt was honest with me, he mentioned that standard ATF doesn't hold up or offer the lubrication properties desired by DC... ... . I'd be carefull about what I put in my transfer case... .



I use a lube center for the engine but we check our own boxes and refill them ourselves... ... using the correct product... .



I'm guessing the lube center guys are either putting in the wrong fluid if they have to add... . or have had to go to DC to purchase the correct product.....

amsoil

makes an atf fully synthetic that is compatible with atf plus 4.

Use any good high quality Synthetic ATF-4 lube, and you won't go wrong.

This has been beeten into the ground but here go's

The stuff in your 6 speed IS NOT ATF. Compare it to the real ATF in your xfer case. According to most accounts, including a TDR members conversation with a dodge engineer, it's 5w - 30 motor oil. Use a good synthetic (Red line & A-oil are good) eng oil and you'll be fine.

Just my . 02

I realize the 6 speed lube has been hashed out several times, that's not the question. I was inquiring if a transfer case with no syncros needs ATF like the older ones. I'm thinking Red Line MTL may be a good compromise.



On the transmission note I put Royal Purple Syncromax in today and it shifts more difficult than the stock Mopar stuff. Looks like it will be drained soon. A 15 mile $25 learning experience! I doubt Red Line would perform much differently but I may try it too.

Hmm, maybe if I was paying better attention eh?

I've got Red-line in mine, Didn't seem to make any difference in mileage but then again I didn't expect it to.
