Hi TomJ
Thank you for your information!
The Windstar has 210,000 Kms (Approx 131,000 miles.)
I have a friend who has a pretty decent code reader. He did not find any codes in the Windstar.
However, reading the symptoms you had with your VSS failure, it seems that my symptoms are not being caused by a failed VSS, which is in line with my thinking.
Readers who have had VSS or TRS failure: what symptoms did you experience, and did you find that the symptoms existed even on cold starts, or did you find that the vehicle drove normally when the transmission was cool, but symptoms returned when the transmission warmed up?
Thanks for your help!
