I did not. This was the first time I had done this and did not read anywhere that I should do that. Will it always leak through there or could there be too much tranny fluid in it?
It looked to me that the TOB assembly just bolted into place and created a tight seal. There is a fluid spot on my driveway about 4" round every time I park it for a while so it appears that it is a decent amount of fluid. Could all that be coming through the seal?
