I was recently able to purchase a workshop manual for the S5-20 5 speed transmission that some of us have. Not sure others are aware of this, but the manual is available new from MIE--a Maerati supplier. The same transmission with a different linkage system was also used in some Maseratis. The manual contains all the schematics including part numbers and assembly/disassemby instructions, special tools, lube recommendations, etc. Schematics of the transmission linkage as used in our cars are also included. The manual is in German, but an English translation is provided on the next page for each illustration. Anyone interested in acquiring one of these is directed to <http://www.maseratinet.com>
