A transmission fluid change will help to restore your system to good working order and is the cheaper option. It is also a relatively simple task that can be undertaken by vehicle owners. A transmission fluid flush is more costly, but will replace all of the fluid and any contaminants that have built up in the system.
At what mileage should you not change transmission fluid?

How much should a transmission fluid change cost?

The cost to have your fluid changed by a dealer, service center or independent mechanic ranges from $80 to $250. The average cost is around $100 for both automatic and manual transmissions.
Why do transmissions fail after changing the fluid?
If you just replace the fluid that’s removed when dropping the pan, the detergents in that new fluid can cause any gum/sludge/varnish inside the transmission to become suspended in the mix of new and old fluid. And if any of that debis finds it’s way into the valve body of the transmission, that’s when the transmission fails.
Should I “change” or “Flush my transmission fluid?
If you’ve got a new or new-ish vehicle, you should perform a transmission fluid flush, change, and refill at about a 40k mile interval (check your manual for exact specification). If your vehicle is regularly used for severe duty, such as towing or hauling heavy loads, that interval should be shortened.
Is it safe to change transmission fluid?
With automatic transmissions that have not been serviced for a while or have no history of service, replacing the old oil with new transmission fluid can actually cause transmission failure. This is because the foreign matter floating in that old fluid (it’s mostly clutch material) is actually helping the internal clutches find their grip.
How often should the transmission fluid be replaced?
Most manufacturers suggest 30,000 to 60,000 miles as the point at which you should change the transmission fluid in a manual transmission. However, vehicles with transmissions that are under ‘high stress’ should change the transmission fluid every 15,000 miles.
