nv4500 tranny fluid
i know the nv4500 is suposed to take castrol syntorque 75w-90 oil. napa dont carry it here. isnt it just a synthetic oil? why wouldnt valvoline full synthetic 75-90 gear oil work

different ratings. you NEED the right fluid or it will take out the trans. You have to get it from chev, dodge, or ams.
|
well im going to run the valvoline stuff for this trip. ive been running the catrol 80-90 gear oil hypoy c for years so the full synthetic wont hurt for 1000 miles, then ill get the good stuff when i get back

yeah. its when the fluid starts to break down that it start messing shit up. There's a writeup on dodgeram.org i think.

from what I understand the Nv4500 reguires a GL-4 fluid. The Valvoline is a GL-5 which has a higher sulfer content. From what I understand the higher sulfer content attacks the yellow metal peices(syncros). However heat also plays a factor. The syncros are in more danger with higher heat because the heat speeds up the process. However a gl-5 fluid runs cooler than a gl-4 so I don't know.
FWIW my dad uses the valvoline stuff and we just replaced his tranny at 300k. Mostly because 3rd gear syncro was gone( it always ground going into gear) and he ended up loosing reverse. They don't carry the Castrol stuff around here either and the Mopar stuff is expensive as hell. |
