no 24mm gaskets at the store. but got the ol $4 funnel with tube for ease of adding new fluid.
I dont have the celica GT-S 6spd tranny, but from the image I got on another forum the gaskets looks metal and not rubber...maybe its grey rubber?
you can see that thread here
now that I think about it, was the "funnel with 1/2" tubing attachment" what I wanted, or do I need one with an actual "hand pump"?
