Dead speedo

Hi guys , not knowing much about EA autos , would a dead speedo cause the auto (4 speed) to go into limp mode ?
I know it sends signals to the auto's ECU but how dependant is it in this input?

Don't know about limp-home mode but it sure makes the gear changes interesting. It tends to hang onto each gear until much higher in the rev range than it normally would than slams the change through. Driveable but not very enjoyable and not recommended for extended periods.

My ED did this - nothing but dirty electrical connectors at the gearbox..

I don't think a dead speedo would cause the gearbox problems, but I'd be checking for oil underneath. From what I know, the transducer, located near the rear of the gearbox, measures tailshaft speed before it exits the gearbox, and sends that signal up to the speedo. They are prone to leaking oil when the inside seals fail, which may cause them to eventually fail, giving you no indicated speed. I've been told it is one of the more common reasons for speedo failure in Falcons.

Not sure if it helps, hope you get it sorted quickly...

Cheers.... Tim
