Won't stay locked in overdrive. Talk about stupid design not allowing for a simple way to change a sensor. The service manager tells me the repair part only costs about $30. However, it is located inside an access cover that is blocked by the cars frame. Need to remove the tranny to get the cover off. That's how a $30 dollar part ends up costing $1000 dollars.
