Interval for transmission flush
Just bought a 1998 V90. Owner's manual says to flush/change auto. transmission fluid every 30k miles (no exceptions provided). But a PDF file I found online states as follows (this is specific to the Volvo V90):
The oil should be changed only in the following instances:
A When the diagnostics system has registered oil temperature too high, (diagnostic trouble code (DTC) 2–3–5).
B The oil smells burnt and is discolored but no diagnostic trouble code (DTC) has been recorded, for example, in connection with heavy, concentrated use.
C On cars used in continuous taxi service and or used to haul a trailer or caravan for most of its mileage, the oil should be changed at a service interval of 75 000 km.
Which is it: every 30K miles without exception, or as needed per A/B/C above?
And how much labor should I expect an experienced independent Volvo mechanic to bill for this job -- less than one hour? (Cost of parts would be about $80 for 8 quarts, right?)
