Just bought this converter and I'm a little worried. 1. Noticed a slight whine on start up. 2. Dropped into gear with a thud. 3. Stalls hard at 1500 rpm. 4. Wont shift up when driven. (or cant feel a shift) 5. Free wheels (coasts) when I let off the throttle. I did some reading and seems I could have a bad converter sprag. Could also have a tranny full of metal and trash from a broken converter. Any ideas out there?
