Do I need transmission flush on 2003 Mazda Mazda6

Also the shop recommends fuel injection service
Mileage 37000

What is the mileage on your vehicle, and what are the reasons the shop is recommending these 2 services?
A transmission flush is not a bad idea if you have never had the fluid replaced, but I wouldn't have the fuel injection service unless you were experiencing driveability problems like rough idling.
I am sorry I did not mention the mileage it is 37000
I appreciate a quick answer. Thanks
