I am thinking of purchasing a 2011 Chevy Impala LTZ with 50000 miles on it. Is it safe to flush the transmission with this amount of miles?


Asked by Sep 06, 2013 at 08:22 PM about the 2011 Chevrolet Impala LTZ

Question type: Maintenance & Repair

I have no idea what the previous maintenance was on this vehicle.  I currently own a 2006 Ford Explorer that I purchased with 24000 miles that now has over 250000 miles which I have maintained on a regular basis with both oil changes and transmission flushes.  Is 50000 miles to high to begin with especially when I don't know if the previous owner was regular with the maintenance?

Not at all, I bought a car with 90K but had some maintenance records. Most items that need attention such as a coolant change and transmission fluid change are done are 50K. Have the car checked out by a local mechanic and if all checks out, purchase it, and slowly start changing fluids and other parts as you normally would. Good Luck!


Read the owner's manual for the change period, some mech. will tell you don't mess with it if there is nothing wrong. The most I would do it drain the fluid, change the filter and refill with tit correct fluid.

I'd leave it alone. Get a vehicle history report such as carfax or autocheck. If it's been serviced at a larger facility it will most likely show up on the report. Mileage is a little high for an '11 model. Could have been a rental or fleet car. Be careful. HTH. -Jim

Check the fluid color. Normal change is around 100K. If it brings peace of mind, change fluid and filter only, no flush unless the oil is burnt and dirty.
