Need a little help. This might be a stretch but I've got a 90 Ram with the NP535 trans in it. What I would like to know is what type of fluid that it takes. Is it a gear lube if so what weight or is it an engine oil if so what type?
 
Also, I did just see TSB stating in can use 10W-30 in very cold conditions to help shift effort.
 
Are you sure its a NP535? I "think" that is the same transmission as the NV2500 If so, my 87 dakota had one, 5spd manual. But it used 10w30 motor oil and not synromesh. That came out latter.
 
5w30 synthetic motor oil if it's low mileage or 10w30 synthetic if it's got some miles on it.
 
Your local O'Reilly has that information in their computer database.

I'm positive it's a NP535. My truck as far as I know was originally a V6 3.9 but when I got it somebody put a 318 in it. And now I just put a 360 in it. So I had the trans out putting a new flywheel and clutch in it.
