My 2001 p-71 transmission started slipping then went into not even moving then grinding mechanically then driving smoothly. could this be electronic?
O/D blinking is a sign that there is a transmission fault, and or over heating within the trans. Since you had grinding as well, I'd say the transmission is toast. Have your local trans expert diagnose it for you. But my guess is your looking at a rebuild. These P71 cars were put through a lot in the years of service from the local police , so no surprise.
Yup, I again agree with Tom, a new, used or rebuilt transmission is probably in your future.
