2003 Chevy Venture 6 cyl Front Wheel Drive Automatic 105000 miles
----------------------------------------------------------------
The transmission shifts hard when going up hills, at high speeds and under a load, even shifts hard when in cruise. Have had it checked, but no physical problems found. Need advice as what to do next. Also, had front ac controlls changeded and now the front fan is no longer blowing as it should be. need to know lkocation of the front ac fan and what to check otherwise if anything.
