17. Oops again, our bad. We failed to heed the warning in the instructions to take critical care with this gasket. We only used normal care and allowed the gasket to slip about 1/4-inch, enough to block half the transmission drain hole (arrow) and kink the gasket. No wonder it leaked like a cheap rain suit. Fortunately, Chris at Baker Drivetrain responded to our urgent call and FedEx'd a replacement gasket.
