It appears mine are ripe for a replacement so I have been preparing the task. I know the special tool for removing those will be handy, and before embarking on this job I wanted to check if anyone did it themselves in the past and is willing to share a tip or two? Any particular place I should order these from?
I also suspect that when removing them it is impossible to avoid draining the transmission oil. I have been reading about it and it is making me a bit nervous. I guess I could either put back the old transmission fluid or refill with a new one and hope for the best. :-/ Considering the leak I will probably have to add some so it is probably not a choice at all. Car has around 110k miles on it.

Thanks!
