All Saab 900 3-/5-d M94- and Cabriolet M95- with manual gearbox


A new gearbox oil has been introduced due to design changes and reduced face area, which puts higher demands on an oil’s temperature resistance.

The new oil has several advantages, such as:
• it withstands temperatures >150°C (302°F)
• it increases bearing service-life
• it counteracts surface damage to gear flanks
• gear-shifting is perceived as smoother, especially in cold weather
• it can be used to advantage in older gearboxes

The oil has been introduced in production from chassis no. V2033279- (3-/5-d) and V7008692- (Cabriolet without turbo) respectively, and V7008812- (Cabriolet with turbo), but it can be used to advantage when reconditioning or repairing gearboxes. In such cases, it is important to read the instructions under the heading “Procedure”.

The filler plug on gearboxes from the factory that contain the new oil are marked with the text:



The new oil must not be mixed with other types of oil but there is no problem changing to this oil in an old gearbox as long as the instructions found under the heading “Procedure” are followed.
