Manual Trans Fluid
 

Hey guys, Finally got around to changing the transmission fluid today. I ran Royal Purple 75w90 instead of the stock Toyota/Scion fluid. It DOES NOT void the warranty to do this. I checked before hand. I noticed quickly, a change in shifting, and transmission noise(or lack of). Recommended change intervals can now be upwards of 50k. Give it a shot, or go with Amsoil as I will next time, just to try it, I am a dealer btw!

Red Line also makes some excellent synthetic transmission fluids. That's what I'm running in mine at the moment. It makes a difference!
