I need some fluid for my manual tranny, Someone told me to go to advance auto and just get atf+4. Then i did research and seen i needed gear oil, Went back on exchanged it for gf-5 but then i seen that if i have brass parts i need gf-4 or what ever, Im not sure if i have brass parts in my tranny. what do you guys use/ suggest. Im tight on money right now -.-

 

Don't use GL-5. It can harm your synchros. Use the GL-4 (assuming your transmission actually requires gear oil. The newer NV3500 takes a special fluid).

 

im so confused the more research i do the dumber i get, Now it says if its below 32 degrees to use 10w-30 engine oil, What should i put in it....

 

Well, is it below 32 degrees?

 

I live in upstate ny, so its about that. but putting engine oil in a tranny seems weird.

 

It's actually pretty common. I would use whatever your manual says to use for the temperatures you expect to encounter.

 

Use the proper gl rated gear oil. (I beleive its 4, whatever the manual states). I used it in my 95 and never had any issues in the extreme cold (Less than 32* down to single digits) however when you FIRST start driving in low temps its just a little goey for the first few shifts.
I wouldn't run motor oil because in the spring I wouldn't want to change it again.

 

Well i looked at my tranny and took some pictures, It says A535 but my book only says np2500 /ax-15 and nv3500

Its easier to see on my iphone when i zoom in but im 99.9% sure its A535

 

I believe the A535 was the np2500 .. I can double check but that's my remeberance from the day ..


Edit.. yes it is known as the Np2500 and was very common with the 2.5 :O

 

Should I use normal or synthetic. Is it okay If I use one quart of gl4 gear oil and 1quart of motor oil or should I just stick with the motor oil?
