Trans flush, coolant flush (5 years), brake fluid flush, fuel filter, air intake filter, cabin air filter
Trans flush (as in change filter and fluid and don't use a flush machine) , coolant flush (5 years), brake fluid flush, fuel filter, air intake filter, cabin air filter
should be doing for maintenance
Nobody needs maintenance. That's what break-fix is forbrake fluid flush is really never needed
