It's not that simple anymore. The NV4500 uses gear lube, the NV5600 uses 30W oil, and the G56 uses ATF+4.

Please explain

When I read the above regarding the "NV5600 uses 30W oil" I think Oh like 30wt Engine oil shouldn't I be using something like





Pennzoil which makes a compatible gear oil that should satisfy my warranty, part# is 3501



Please explain as I do want to R&R my transmission oil



Thanks

 

[klenger]

You are correct. The NV5600 does not use simple engine oil, but I think it is 30W. See http://www.klenger.net/dodge/general-reference/nv5600-fluid/index.html on my website for more info on the Penzoil stuff.

What has been used by TDR members, to briefly summarize (speaking of NV5600)



Amsoil 5w30 diesel engine oil (OK results but drawback is it's- engine oil not gear/transmission oil)

Redline MTL (most pretty happy, best viscosity match, meant for trannys)

Royal Purple Syncromax (good results for most, 1 guy killed transmission, thin lube closer to 20wt oil)

Amsoil MTF (30w lube designed for transmission, haven't read much feedback yet)

 

[DPKetchum]

The Amsoil MTF is a differance in night and day over factory fill. I think its like a 5w30. But states its ONLY for the nv5600 manual transmission as well as a few other manuals. It is NOT engine oil.

did the royal purple in my 01 Automatic rear end front end transfer a year or so ago. has worked great. The 03 6 shooter has 67000 on it and probably still has original factory lub (i just bought it. Not sure what i will put it it. do a lot of heavy towing

 

[Dieselhed]

I use the Royal Purple as well and really like it.

48re transmission

thanks for the replys

looking for fluid for 48re

In warantee or not? If in, you should run the ATF+4 from Dodge or an equivalent.

second the amsoil mtf, good stuff. The big 5600 shifts smooth as butter now. I changed it at 15k, but will probably wait until 45-50k with the amsoil.
