I noticed today that my at light blinked 16 flases after I staryed the car. I ran the at diagnostic & had a loner 7th flash. That code says lockup solenoid is shorted or disconnected. What would cause that? I suppose the solenoid in the valve body could have gone bad. I replaced the tranny with a good used one a few months ago. I installed a transgo shift correction kit along with a new filter at that time. Car seems to run & shift like it should. What would this cause & would I be able to tell? Fluid looks brand new, no slipping or anything else is going on.
