I just bought a bottle of slick50 manual tranmission additive, and it says add to the gear box. I only see the auto trans fluid fill up marked in the rx8 manual. Can anyone tell me where the manual tranission one's is? Is it the same at the clutch/brake fluid? Great if anyone can post pics as well. Thanks

 

There is a thread somewhere on here with pictures that someone did when they changed their manual transmission oil. The filler plug is on the side of the transmission. The only way to get to it is from under the car.

Here's a thread to check out:
