Not sure about the price but I anticipate it will not cost the bank. So perhaps wise to have one as a spare on your own stock. 

Hi all-
Out of necessity, I’ve created a replacement for my faulty 400i automatic transmission microswitch (Ferrari p/n 106603), which activates the downshift solenoid on full throttle. If you are in need of the switch and haven’t been able to find a good assembly, I can make more and will probably create a listing on eBay so it’s easy to find. I understand it to be used on 308, 400GT and 400i… I think the 412 went to a different design.
