Transmission oil change
I'm changing the oil in my 5spd trans today... I feel stupid for asking this question but even in my manual I can't find the answer.... What oil do I use?
In the manual is says gear oil and then contradicts itself and says 25w motor oil...
Can I get a recommendation on what oil to use, please?

Well looking at the transmission and considering the age of the vehicle it may have been replaced at some point as it looks newer and still has the "fill" sticker intact and it's also painted. So it might not even be the original trans. If I get a look at the ID will that tell me? How about some pics?

Ok, so after doing some research, I found out some info. When I read it I actually remembered reading this before but I forgot...
The A535 is the older New Process Gear version of the New Venture Gear NV2500. Same transmission, different name when the company changed to New Venture Gear. These transmissions use 10W-30 motor oil or 10W-30 synthetic motor oil.
If you think it was changed by the PO, you need to be sure what it is, cause the AX-15 takes Mopar 75W-90 API grade GL-5 gear oil or equivalent. The NV3500 specifically takes Mopar Manua Transmission Lubricant P/N 4761526 or equivalent (I believe AMSOIL makes an equivalent).
Like I said before, you need to be sure, cause mixing up the fluids WILL cause failure.
