10 Suburban -Transmission Fluid and Maintenance
3 Answers
Do Not do a flush, have the pan removed, fluid and filter replaced. Flushing the system at the local jiffy lube takes all the contaminates that the filter caught and blows them back into the transmission completely defeating the purpose of a filter and putting contaminates where they don't belong.

I would have the fluid and filter changed yearly. Cheap insurance since you heavily depend on the truck.
