I remember it costing around $125.00. It works on my vehicle from the early nineties, my vehicle from the early oughties (as in 01), and a vehicle from the early twenty teens. I wonder if the scanner would have pointed to the speed sensor before and after replacement. I wonder if the manual contains enough information to allow you to test the sensor in or out of the circuit?<br><br>Francis Robinson aka "farmer" Central Indiana USA AT List Member (robinson46176@gmail.com); The 2005 Chrysler Town & Country I bought several years ago from an individual ran and drove great but then went into "limp" mode on the transmission. I did some studying and decided that it was the input speed sensor. I bought a new one and put it in. Zip, no change. OK, I was wrong. I took it to a busy mechanic friend and told him the things I had checked and about the new speed sensor not helping. I've known him since he first started and have used him for electronics problems a number of times. He is one of the good guys, always treated me well and while he is not free :-) he has always been fair. (He has retired now dang it. His son-in-law took over and I won't take anything to him.) Anywho... He called a bit later and he found that the new speed sensor was defective... He changed it and charged me but it was reasonable. No other problems. I had about strained my brain looking at stuff... I had even done a fluid and filter change just to get in there to look at stuff. It has done well in the years since. We have traveled in it quite a bit.<br><br><br><br><br><br><br><br>_______________________________________________<br>AT mailing list<br>AT@lists.antique-tractor.com<br>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com<br></body></html>
