P0700 is just a generic code stating there is a transmission fault present. That is just there because the other code is there. Have you done any work on this thing lately>??? Shift kit install>???
Al, all you had to do is ask. I know it's a little late now, haha but I always have a bunch at the shop. Hope all is well and you had a good holiday. -Mat-
I feel like I have something planned that weekend, just can't remember what.
If I am free I will take a ride up and hook some weight up to the Fatback.
Like Mike said, those drain plugs were not factory.
I have yet to seen an aftermarket converter rebuilder install a drain plug either.
I'm not that old though.
