Transmission oil change due to time?
I'm buying an Alfa with a C7 and an Allison 3000. The tranny had an oil change 4 years and 25k miles ago. Do you change the trans fluid due to time?

If the trans pan has a drain plug, I would drain and refill the pan every time you change the oil.
There is no reason to do that and it would be very costly. Allison has a maintenance and change schedule and that is what should be used. My changes are based on time and not milage and at a cost of 310 for parts and about and hour of labor that is a cost of about $435.00 parts and labor.
