I was having no problems with the transmission but thought it time for a fluid/filter change at 160k. Now I'm getting a flashing o/d light and a p0741 code. I've read thru a number of posts and still am not certain how to approach this. Is it possible I damaged the TCC solenoid? I had a devil of a time getting the pan off and on due to it being jammed right up to the cat. Should I attempt to replace that solenoid (and the EPC for good measure). I understand the can be replaced without removing the valve body. Anyone have any ideas? I just can't buy its a coincidence that the TC went out because of a fluid change. This has been discussed a little on another thread I had about the difficulty of getting to the pan. I'm hoping posting here will bring more focused help on the problem. Someone posted a set of instructions for electrical testing but they sort of ran over my head, sorry.
