It is supposed to exit the speedo and go to the TCU as a digital pulse increasing with speed. My signal is 1/2 the frequency it should be therefore the shifting is very late. I also read that when the signal is not present the TCM will default to a calculated value for shift points but the shifts will be rough. I tried disconnecting the signal and all of a sudden shift points were more or less normal but of course a fault code is set and the TCM soon shifts to Limp home mode. My conclusion is that the analog to digital conversion in the speedo is bad and will be trying a replacement speedo. I am going against the advice of several seasoned Volvo mechanics. They tell me to replace the tranny but I respectfully have disagreed with them. I maintain that the tranny is simply shifting when its told to and that the problem is with the electronic control. Will keep posting progress. -- David Hunter Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.
