My 95 bronco's e4od is shifting hard in mostly all gears. It slams into reverse. I disconnect the battery, it's fine for maybe a day or an hour. Using the code scanner, I received a 628(converter clutch slippage). I have replaced the valve body solenoid assembly and the MLP switch. I have erased the codes, but I am still getting a 628 in the continuous memory after I drive it for a while(a day or an hour). Any thoughts or ideas on this would be appreciated. Thanks, John

 

sounds like a junk convertor, or the starts of.
