I haven't thought of this part and I assumed it would be the same size as for the engine oil drain plug...... Remember to have a new washer on hand also. It is not the same size as the engine oil drain plug washer.
+1 there Freddy. Except I used jacks. I am going to do the filter every other tranny fill. Of course while I was buying the tranny fluid at the dealer I asked about the filter. He looked at me like I was full of **** and said it didn't have one. When I got the belly pan off to do the oil change the tranny filter was stairing me smack in the face. Just tell them what you want to buy and leave. Most of the parts people haven't been under the hood and if it doesn't jump off the screen at them then it doesn't exist.Just did mine today and it's easier than the oil. A lot of smouge on the magnet tho. I'm going to get a tranny oil filter and replace it in the next month because the smouge worries me. Only had 18k miles on the fluid and the color was starting to darken. Tools needed philips screwdriver, 3/8's breaker bar, catch pan, 3 qts honda fluid. I drove the car on ramps.
