get the code and post it here..

 

Will the code be stored after the car is turned off?

 

the code will remain until it is cleared or the problem is corrected

 

Since my original problem I have changed the AT Control Unit (ATCU) (got a rebuilt), when I did that I developed a new set of problems. I checked the code but there's nothing stored. I did swap the ATCU again, so far it looks like the intermitten shift problem is cured.

Several months ago I had the speed sensor changed. It seemed to be working fine until I swapped the ATCU. I thought they were connected but the problem remains the same after the second ATCU swap. At 3K RPM it's showing 52 MPH, kinda slow. I did observe the speed drop 8 MPH while on the Interstate. Also when I come to a complete stop the odometer will show 2-5 MPH. Looks like another Speed Sensor to me, any ideas?

 

Hi I am having the same problems the "S" light blinks. It seems to shift from 1 to 3 and that is it. How do I get the code?


thanks
