Manual Transmission
Manual transmissions installed in the 5 Series are normally
filled with a "Lifetime" manual transmission fluid
(BMW MTF
LT-I) and do not require periodic fluid changes. Transmis-
sions filled with MTF LT-I lifetime oil are identified with a yel-
low label near the transmission fill plug labeled "Lifetime Oil
MTF-LT-1".
