have a 1992 900T with 5-speed. I want to change the trans oil
at her 125,000 mile service which is coming up soon. As you know,
that model year does not have a drain plug so I will drain via removing
the rear differential cover. I will use a new OEM gasket and 10W-30
motor oil. My question is, what is the proper torque for the differential
cover bolts? My guess is 13 ft-lbs to 15 ft-lbs. Is that right?
Saab factory manual states the all 8 mm diameter bolts on the
trans case should be torqued to 17-21 ft lbs. When I do any trans
work I torque all cover bolts including the differential cover to
18 ft lbs. This has worked well for me. I am also glad to
hear you plan on using a OEM gasket and 10W-30 motor oil. This is
the proper way to do this job.
