No matter what brand you choose (I prefer Royal Purple), add some Lucas Oil/Transmission Stabilizer. That stuff works great and will give your shifting a much smoother feel!

whoa! whoa!

There are two weights you use depending on whether you have a "World Class" or "Non-World Class" T5!

Use too thick of an oil in the world class t5 and the bearing are going to run dry because the oil holes are much much smaller...

I'll post a link as soon as I find one!

According to the previous owner its a World Class. Is there anyway to check?

t-5 history link

One last piece of important information. ALL World Class T-5 use ATF oil and NOT heavy gear oil or Redline MTL! All NON-World Class T-5 use 70 wt gear oil. We recommend high quality Synthetic oil as it lasts a long time and over a larger operating temperature. It is important to change the oil in your transmission based on how you use the vehicle. If the vehicle is your daily driver then changing the oil every two to three years is fine. However, if the transmission sees regular track duty and pushed hard, then once or twice a year is in order. When we rebuild transmissions, we can tell when the oil has been changed often as the parts are much cleaner with less over all wear. There is no filter inside the manual transmission only a magnet at the bottom to pick up the metallic particles in the oil, the only metallic parts in a transmission is the gears or bearings. Oil is cheap, transmissions are not!

Hopefully that helps...

It seems to be based on year and application. If it was originally out of a 4-cyl - forget it, not a WC. But from behind a 5.0 after 85 or 87.. should be - I guess.
