Quick, probably dumb questions from a transmission novice
I have those tools, and have never been able to use them. Just not enough room above the trans to the floor of the car. I find it easier to drop the pan, valve body, drive the old seal out from the inside, and press the new seal in with a bolt, nut, and a couple of washers. Hardest part is getting the seal to start going in straight. Then clean the pan, replace valve body/filter, pan and refill. Even jerking around, usually done in less than 1 hour.
