Ok got 100k on the truck now so i wanna change ALL the fluids in the truck. Which fluids and oils should i run? What brand and weight and etc.....

Motor oil: Rotella
Trans fluid: ????
T-Case fluid: ????
Front and rear diff: ???

Thanks
Sean

 

Motor oil that is 15/40 or 5/40 Ci4+ or Cj is fine
Trans will be the Syncromesh for the 04.
Transfer case is ATF+4
Front and rear diff is 75/90 GL5 rated synthetic. 140 weight if you tow heavy

 

well the truck is a manf date of 03 but late 03 does it matter on the trans? its a NV5600.

 

nope change it about every 6 months or 50k and it will last and your difs about every 50k

 

no i mean the fluid for the trans

 

If you have the NV5600 then Syncromesh is the one you want.

 

where do i get it from and how many gallons

how much for the t case and diffs

 

I think a lot of guys with NV5600 also run Redline MTL.

 

don't forget 100K is time for a coolant flush too

 

Owners manual has a page for capacities. T/C holds around 2.5 qts, rear diff. is about 4 qts., front diff is about 3 qts.

 

I had to replace my waterpump at like 90k so thats good.

 

Consider changing PS fluid and brake fluid. Both are benefital services for life of components.

 

Ya gonna change brake but how do you change PS

 

For the PS I use a big syringe with a hose and suck out the reservoir every 50k or so and replace with new fluid. That method gets most of it.

 

I run Amsoil products through my entire truck, and I love them.
