Thanks.
I actually did change out the speedo gear as well. I don't remember for sure about the shifter seal, but I'm pretty sure I did as I purchased the entire gasket kit for a 400. I actually posted about the issue here before I did the work and I did as everyone on here advised. Also when I did do the job, I couldn't for the world see where it was leaking from. I know part of the problem is that I don't use the truck enough and the fluid tends to leak when it seeps down into the tranny pan. I guess I can try and get underneath again to see where it leaks but it's hard to see because tranny fluid is so thin and just kinds runs down.
I wonder if it couldn't be the front seal where the torque converter mates?
