misfire chk? replaced plugs and wires about 30k mi ago when purchased. if plug(s) is prob wouldn't misfires happen at all rpm's/speeds? or could ignition control module unit be suspect? Had another Mechanic run diagnostics test (today) and he confirms P0742 & P1811, both transimission faults but gets no motor/engine codes. appear to be headen for rebuilding Tranny job. any other thoughts or does this prognosis sound correct? thnx.
