Converter drainback is a perfectly normal occurance, there are service bulletins advising owners to start in Neutral instead of Park.
Thanks John.
So by extension, this has been a known problem for some 30+ years? Even new cars off the showroom floor may have had it? Or does some normal trans or converter wear eventually lead to this? I've got a stock 75 /6 with a 904, and a shift kitted 70 340 Swinger with the original 727 that do this...
