im coming up on service interval for my rear differential and im also planning on changing the manual trans fluid while its up in the air. ive been in and out of forums but am not getting a clear answer on what fluids to use. i also dont have the owners manual, if i did this wouldnt be an issue. anyways i have no limited slip in the rear, and its also a six speed. any input would be appreciated thank you!
