Re: error code 628 converter clutch error (E4OD)
Error code 628 refers to too much converter slip, i.e. your converter is bad, not necessarily your entire transmission. The high price for the rebuild is about 75% labor. You can take the trans out yourself, and get it rebuilt at a shop for less than $400. Or you can pull the trans out, and replace the converter only for alot less. Call a shop and see what the price of a rebuild is if you R&R the trans yourself.
