could someone help me out here? took my 07 lt 5.3 to tranny shop to have it rebuilt, was slipping and had an iss code. well guy calls and said they have everything done but cannot get rid of the iss code, they put in a new sensor but still has the code. i did the afm delete on this and had it turned off in computer and never had any issues til coolant got into the tranny from pinhole in radiator. hes thinking the afm delete or possibly fried ecm is whats keeping the code. anyone have any ideas i can tell him to try??
thanks for any suggestions
