hey guys i just have a couple of questions about my tranny...

i serviced my tranny earlier and when i drained the fluid out, it looked like brand new oil that came out. does tranny oil wear out like it does when it is in an engine? and what kind of oil is supposed to go into a 96 gsr's tranny? and i put a full synthetic 75w90 into the tranny. is that bad or will it be ok?

any feedback will help thanks!
