It only $12 buck at advanced. They don't like water and heat.
You watch closely to speedo it will moving but sometime it tick like clock do.
When you see try hit top dashboard did it bounce crazy.
Keep driving with issues will ruin transmission fast.
yeah the speedo was dancing all over. Started at about west branch, and by the time I got to petoskey the speedo wasn't even working at all just fluttering all over. Got in the truck to come home and the OD Off light blinked for about 10 minutes, then it stopped blinking and everything went back to normal from petoskey all the way back home to fenton. The truck drove as normal the entire time, even when the speedo was acting wonky. Haven't driven the truck since.
Bought the sensor and replaced this morning. we'll assume this will fix it.
