Re: 4L60E Trans Shifts hard from 1st to 2nd?

What did the rebuild shop use for the valve body? Did they yse a shift improver kit? If so, then you may have a set of spring loaded chck balls that are upgraded to have it shift harder. Also the Governor may have been upgraded to a "Corvette" style governor, which will enhance the shift.
