F 13/F 15/F 17 gearshifts: For F 13/F 15/F 17 transmissions the transmission number is punched onto the end shield (arrow). The number combination is identical to those on transmissions F 10, F 13, F 16 and F 20 (D 7827, excluding position "5") | 
|
Transmission Identification (Continued) F 18 - manual transmission: For identification of the F 18 and F 18+ transmissions, the end shield is fitted with an identification plate. The identification data is visible from the left wheel well (arrow). |
