I don't think you can bypass a speed sensor. It provides a constantly updating stream of input to the computer.<P>I don't recall a sensor in the transfer. There is one in the tailhousing of the trans. There is a solenoid that is located in the transfer. Have you checked that? A sticky solenoid might cause what you have described.<P>I broke down and bought the AT service manuals when I was planning my AT/xfer swap. They are an excellent investment.<P>Phil<P>------------------<BR> <A HREF="http://pjohnson.netgate.net" TARGET=_blank>http://pjohnson.netgate.net</A>
