2002 cummins 6 speed transfer case oil
 

Hey guys looking to change the transfer case oil on my 02
Cummins ... It's a six speed any suggestions

Should be ATF +4 for the T-case..

I'm sure you can use other stuff in the t-case though..

ATF+4 or dexron 3+ will do fine.

Thank you I appreciate it

How many quarts does she take

think it's supposed to be 2.5 but I would get 4 to be sure... fill it up till it comes out of the plug then cap it real quick.

I use royal purple ATF in mine.

2001-2005 Six-Speed NV5600 Manual Transmission

To quote from the Owner’s Manual, “This transmission is filled with manual transmission fluid at the factory. This fluid does not require periodic changing. If it is necessary to add or change the fluid in this transmission use Mopar manual transmission fluid (Mopar part number 4874464 or Texaco 1874). These are the only lubricants recommended for use in the NV-5600 transmission.”

This is another example of a lubricant that you will not find at the local auto parts store. Discussions with Mike Patton, owner of Standard Transmission and Gear, revealed the following: The New Venture 5600 gearbox uses a synthetic 30-weight oil. From New Venture literature we know to use the Mopar 4874464 part number.

However, Pennzoil Synchromesh, 30-weight, synthetic fluid has been confirmed as an acceptable alternative. The Pennzoil will likely not be easily found, but they should have it in stock at Standard Transmission. (800) 783-8726

Hope this helps.

Here is something that I thought may help clarify which fluid to use in your transfer case. After reading what others stated they are using, I thought you should be aware of the fluids for the 2005 Dodge Cummins transfer case.

Best regards.

2005-Current Six-Speed G56 Manual Transmission
The lube oil recommended for the G56 transmission is Mopar ATF+4. Mopar ATF+4 is readily available at your local auto parts or Mopar dealership.

AUTOMATIC TRANSMISSION FLUID
For the automatic transmission the latest DaimlerChrysler specification calls for the use of “ATF+4, type 7176.” Unlike the scenario of GL-4 versus GL-5 (in which the former is good but the latter is not better), the latest ATF+4 type 7176 can safely be used in all previous 47 RE/RH automatic transmissions.

In this case, logic prevails—if +3 is good, then +4 is better! This information was verified by D/C’s customer advocate personnel. If you have any doubts about the correct transmission fluid, consult your Owner’s Manual.

Briefly the reason Dodge has the +3 and +4 designations is the highly refined base stock and friction modifiers that are specifically designed for the Chrysler transmission.

he wasn't asking about what fluid goes in his transmission. he was asking about the 4x4 transfer case, which takes ATF. :tu:

Agreed. My mistake.

Thanks guys! Your all great....
