Additional Notes

  • The Alfa Romeo 166 936 uses a transaxle layout across all listed engine variants, meaning the manual transmission and final drive share a single housing. This arrangement is common in front-wheel-drive vehicles with longitudinally mounted engines and directly determines the fluid capacity required to service the unit.
  • The 166 2.0 TB (2003-2007) transaxle holds 1.7 liters of manual transmission fluid, while the 2.0 TS across both the 1998-2003 and 2003-2007 periods holds 1.6 liters. The 100 ml difference between the TB and TS variants reflects a distinction in internal transaxle volume despite both being 2.0-liter four-cylinder applications.
  • The 2.4 JTD diesel engine shows a capacity shift between generations. The 1998-2003 variant specifies 1.6 liters, whereas the 2003-2007 variant rises to 1.7 liters, indicating a revised transaxle unit was introduced at the 2003 model update.
  • The 166 2.4 JTDm 20V (2003-2007) carries a notably higher transaxle fluid capacity of 3.2 liters, substantially above all other listed variants. A capacity of this magnitude typically points to a larger or more complex transaxle assembly, possibly incorporating a different gear set or additional internal components compared to the standard JTD unit.
  • The 2.5 V6 engine, listed across 1998-2003 and 2003-2005, maintains a consistent 1.6-liter transaxle capacity in both periods. The 3.0 V6 (1998-2003) steps up to 1.7 liters, and the 3.2 V6 (2004-2007) rises further to 2.0 liters, showing a progressive increase in transaxle fluid volume as engine displacement grows within the V6 family.
  • All ten listed configurations share a uniform check interval of 80,000 km under normal use conditions. A check interval, rather than a full drain-and-fill interval, means the fluid level is inspected at that mileage point rather than automatically replaced, which is a standard practice for sealed or semi-sealed transaxle units.
  • The normal use condition applies to all listed rows without exception. In fluid service terminology, normal use typically refers to regular on-road driving without sustained heavy loads, frequent towing, or extreme temperature exposure, as opposed to severe use classifications that would typically shorten service intervals.
