heard alot of different views on what oil to use in this nv 4500. dealer even said they switched them to full synthetic atf+4.did not want to try that. what have you guys been using? 

There has been several conversations this year about which oil to use in the nv4500 transmission; here are 2 of them . I hope this helps,

 

 

 

Tractor transmission fluid ?

Redline MT-85 is supposed to be good stuff. I use stuff from Blumenthal out of Oklahoma city, they used to ship but not sure anymore

Valvoline MTF is good.

Mobil 50 SAE is good.

PenzOil Syncromech is good.

 

I've used Mobil 50 SAE in my truck no issues. Over powered 5th gear and ate the teeth off the gear. I've done several services on customer trucks and used both PenzOil and Valvoline both and no issues at all for the NV4500. 

 

No need for Redline and AMSOil fluids. There is a wide field of fluids that work in our trucks. GL-4 is the only requirement. Viscosity wise even the Dodge dealer will fill with ATF+4. Personally is too thin. 

 

Gotta remember I work on several truck and give options to my customers on what they want to use. I stay and touch and so far no issues.
