Hey guys you guys have helped me a lot I would first like to thank you , you guys probably saved me a lot of money.

Now I switched my 3rd gear pressure switch about 1 week ago runs smoothly , today I was driving and my d5 light was flashing and I went to autozone and ran the CEL code. I never cleared the 3rd gear pressure switch code after I replaced the part but the same 3rd pressure gear switch code came up and the input speed sensor came up . I bought the switch and speed sensor on eBay and I haven't installed the speed sensor but the pressure switch has been.

What can be the problem?

 

I just disconnected the battery and the CEL hasnt been on the last 5 miles lets he how long this lasts.

 

Better to read again, sometime even light not on but code is there that's what happen to me. If there just delete it, it won't hurt your car.
