Within the last year i replaced both pressure switches on my 04 TL. In the summer I had a single occurance of my drive light blinking green. After having the code read it came up as the 4th gear pressure switch that I had recently replaced. The shop reset the code and I've had no problems for about 4 months now. Since the switch was new and hasn't given me any problems since that one time, I was wondering if its something worth stressing over? Car drives just fine. Any reassurance/advice would be appreciated.

Thanks

 

Anyone? The code was only thrown once through the blinking drive light. The switch was new and hasn't produced a code since being reset in august.

 

try to drain and refill your ATF once

 

Thanks for the response. After having the code reset I also did an atf drain and refill along with my oil change.
