Sometimes it's not the pan but leaking from somewhere else and collects at the pan gasket and tricks you. Suggest you thoroughly wipe it down and see if it's leaking from somewhere else. Mine was leaking at the shifter shaft seal which is common. The other place is the dipstick tube
Yes, I've always had a leak from the speedo-cable assembly at the trans. I've replaced the seals and nothing seems to work. Perhaps the speedo gear housing is bad?
re: pan leak; much like the engine oil pan, once it's over-torqued and distorted, you have to remove it and hammer out the deformed areas around the bolt holes. Even with a new gasket, there will be uneven compression on the seal surface. the bolt torque is critical and is the reason I always use a torque wrench.
