I just got a printout from the dealer (using my VIN) and it lists all the features that went into building of this truck. Right down to the date it rolled off the line.

Q: The sheet is showing I have a DDX 5-speed HD Manual Transmission
But, when reading the service manual for the correct lubricant, they show 3 types.

1) NV3500
2) NV4500
3) NV5600

How can I tell if which one I have on my truck?
Any recommendations on what to run for lube? The book shows its only as current as the printing... So.....

 

you have the 4500

 

How do you know? Not saying you dont, just wondering how is all....

Thanks,

 

The NV5600 is the 6 speed which you don't have, and the NV3500 was on the gasoline engines only on HD models, as far as I know.

 

Would this truck have limited slip differential? Reading the service manual, replacing fluids with "fresh" and giving it a complete tune up you might say.
The service book is showing me the types of lubs to use in the following

Differential lubricant...
Limited skip differential...

Thanks

 

because im a freakin genius

as for the limited slip, that could be in the glove box (on a label) could be on a tag under a bolt on the rear end cover or you could jack up your rear end and turn one wheel by hand. if the other turns the same way, its a limited slip, if it turns the other, is an open differental

 

Glove box says "Axle Ratio 3:55"
Rear end cover only has some numbers.
Jacking up the truck in the past.....I remember then turning opposit directions...So, Im gonna say "OPEN DIFF" lol

Thanks again!
