Background
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-older-gearboxes
The oil has been introduced in production from chassis no. V1021673- 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: "USE ONLY SAAB OIL NO 8748733"
When changing the oil, the filler plug must be changed. However, the new plug does not fit on gearboxes in cars older than model year 1994.
Important
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.
