I have a torque converter drainback issue on my TH 400. The tranny was rebuilt about 8 years ago and the torque converter is a B&M I got from Summit about 12 years ago. I know the simple fix is to drive the truck every week, but I don't think it's normal for my garage floor to be covered in tranny fluid if I don't use the truck in 2-3 weeks. When I go to check the dipstick it marks very high. The tranny is top notch other than that it runs like hell-it's a TCI racing tranny. Would a new torque converter solve the issue? I replaced all seals on the tranny last year that I could get to without taking it off, but the problem is with the tranny getting over full by the fluid contents of the converter. Any info is greatly appreciated. Thanks.
