4L60E line pressure problem 93 chevy truck with 4L60E trans, trans rebuilt in june 09, less than 1000 miles...all of a sudden shifts hard into gear and especially on 1-2 shift. trans guy locally said at first a solenoid now say correct voltage not getting from pcm to trans, NO CODES or SERVICE LITES etc. what could this be .. he wants to put in pcm but chevy dealer said no codes/service light and no codes stored means pcm ok, what are your ideas to suggest trans guy look at. thanks.
