Engine and Transmission Number Locations

Text and photos by John Chatley

The first three photos show where to find the engine serial number, case casting number, engine type, and case matching numbers for each piece of a three-piece 356 engine case. The fourth photo shows where to look on the underside of the transmission housing for the transmission number, transmission type, and transmission build date, as shown in the fifth photo (644 transmissions) and sixth photo (716 and 744 transmissions). These locations are consistent for all 356 models, though early 356s with two-piece case engines are somewhat different.

[Editor: if anyone can provide photos of two-piece engine cases showing the relevant numbers, as well as earlier 356 transmissions, I will publish them here.]
