could someone give me the fluid capacities on the 2003 dodge ram with cummins for the 6 speed manual tranny, the front and rear differental, and the transfer case??

 

Don't know which one you have. Hopefully this covers yours If not let me know.

Transmission
NV5600-4.9L(9.5pts)
NV4500-3.8L(8.0pts)
Transfer Case
NV273 or NV271-1.89L(4.0pts)
Front Axle
9 1/4 AA- 2.25L(4.75pts)
Rear Axle
11 1/2 AA - 3.62L(7.65pts)

 

I haven't done the differentials or transfer yet but just did my NV5600 on Thursday and all I could get in it was 4 quarts. I drove it about 100 miles yesterday so now I will crawl under and check the level this weekend.

When I put the 4th quart in it started running out the fill hole as I was hitting the bottom of the bottle.

 

Don't know about the 2004.5 but the information came out of Dodge's DR 2003 Maintenance manual.

 

When changing the fluid in the NV5600 you have to park it nose down or jack up the rear.

 

Spreadsheet info I've kept on my 04 2500 with 6spsd, 3.73 rear 4x4 since Jan 2004.

Engine Oil (11 Qts/ 12 w/filter)
Man. Trans. NV 5600 ( 6 Spd 9.5 pts/4 qts)
Frt & Rear Axle (3.73) (up to 5 pts frt & 8pts rear/8 qts)
Transfer Case (up to 5pts/3qts)

Just did the rear end and transmission last Friday evening and it was 4 quarts in each with oil just dripping out of trans and about 1/4 inch below rear fill line.

 

thanks fo rthe reply guys, just need to know how much of what fluids i need to order, since i dont drive but about 5,500 miles a year and dont tow anything i figure better to pay more and get the good stuff for the drivetrain, so whats better REDLINE OR AMSOIL?

 

I used Royal Purple Synchromax as it was listed as fitting the part number and the MS #. Redline had MTL listed but I have read where people have not received a satisfactory answer on using AMSOIL.

I emailed Royal Purple and asked how I would be able to show that they met the OEM requirement and they replied that if DC was a problem then they would stand up for their oil as long as it wasn't contaminated or low when the failure occured.

When I changed out the tranny I jacked up the rear end so the truck was a little nose down and let it drain for about 2 hours. Then I filled it up while it was in the same position. Drained the oil into a 5 quart jug and it only came up to about the 4 quart level.

 

Amsoil does not make a Tranny fluid for the 6spd. The tech line recommends motor oil? That's why I run the Redline MTL.
I don't jack up the vehicle, just roll around underneath. The PTO bolt is already at the lowest point of the transmission.
