The manual trannys should hold between 3-5 quarts or liters. Some
remains in the tranny if you drain it with the tranny level. With the
tranny hot and the front raised most of it will drain out if you wait,
in my experience. Bentley claims 1.5 remains in a Syncro tranny.

 Syncro tranny - 4.7 quarts,  page 34.19
 Early 4 speed 091 - 3.7 quarts, page 35.2
 Diesel 4 speed 091 - 4.2 quarts, page 35.32 or 35.60
 WBX 4 speed 091/1 - 3.2 quarts, page 35.32 or 35.60
 5 speed 094 - 4.2 quarts, page 35.62
