Starts ok


First few minutes of operation OK Everything functions


As the temp gauge hits normal the speed control quits and trans makes slamming downshift to 2nd.


Erratic operation and occasional runawy continues for about 10 minutes.


After about 10 minutes trans operation returns to near normal but speed control remains inoperative.


Wiring manual shows a transmission oil temp feed to the computer but I am unable to locate actual part.


Any info or suggestion appreciated.
