Could also be a combination of 2 issues, the V.S.S. should have nothing to do with the power steering. I have seen the same shifting issue combined with the spedo & cruise be caused by the Transmission Range Sensor. This can cause all sorts of problems, but I have also seen a faulty alt. cause the same type of concerns. Sometimes it may be more cost effective to have a factory trained tech diagnosis this for you, otherwise your pocket book goes down with each new part and your parts store just gets more money... Just something to think about. - Phish |
