Ferrari has always produced manuals for their dealers, and owners, to assist them with vehicle repairs, servicing and spare parts ordering. Up to about 1970 these were almost always in the form of single bound books which required complete new editions to be printed when changes were made to the specifications of the model concerned. After this time these publications (unless dealing with specific features) were more likely to be in the form of ring binders with all the information on loose pages which could, subsequently, be updated, replaced or added to as technical development of the car progressed. The transmission was the Turbo Hydra-Matic (THM - registered trade mark) developed and produced by General Motors in the USA, which coupled a three-element turbine torque converter to an epicyclic (or planetary) gearing system, providing three forward speeds and one reverse.
The book, measuring 21cm x 29.5cm , has 56 inner pages of technical information and instruction, dealing with the operation, servicing and fault diagnosis procedures for the unit. The text throughout is in Italian and English only.
The factory catalogue number on the rear cover reads Cat. 157/78 , but there is no specific print date or quantity stated.
