I recently acquired a low mileage 03 Chevy impala. The car is in fantastic shape overall. Some minor issues with the cooling system but other than that it is literally like a brand new 13 year old car.
My question is I'm going through the car and want to change all the fluids. The recommended service interval for this particular transmission is 50,000 miles. The car currently has 41K. There seems to be a lot of mixed opinions on changing the fluid or leaving it alone. Since its under the recommended service interval it should be ok. But I know it was generally used for short trips and up until last week probably never left the Tampa Florida area it's entire life. Fluid seems nice and red and no issues at all. Just like being proactive with maintenance. Thoughts?
