DIY-safe driveway job
A change dumps what gravity will give you. A flush exchanges nearly all of it through the cooler lines. On a healthy, regularly serviced trans, a flush can be fine. On a neglected, burnt, or mystery-history box, a flush can be the job that makes it slip. This video is the sentence you need before you initial that line.

Can Changing your Transmission Fluid Cause Damage?
ChrisFix draws the change vs flush difference and when a flush can move debris in a neglected valve body.
Watch on YouTubeIf you are not DIY · say this instead
Do not machine-flush this transmission unless you have inspected the fluid and the maker calls for it. I want a drain-and-fill or a diagnosis first.
Ask at the shop
Ask to see the fluid and which procedure they priced. “Transmission service” is not a procedure.

Fluids
Transmission drain-and-fill (not a machine flush)
A drain-and-fill replaces the fluid that actually falls out of the pan — often 40–50% — plus the filter if the pan comes down. It is the conservative service. A machine flush pushes fluid through cooler lines and can move debris in a neglected box. They are not the same line item.
Fluids
Map every fluid before you authorize a package
Oil, trans, coolant, brake, power steering, and washer are different jobs with different intervals. A shop multi-point that wants all of them at once is a menu, not a diagnosis. Learn what each jug is for so you can say no.
Fluids
Change the engine oil and filter
Oil is the engine’s blood. You drain the old, swap the filter, and pour in the viscosity printed on the cap — not whatever is on sale. A driveway oil change is the first real job most owners should learn.
Fluids
Check and top off coolant the safe way
Coolant keeps the engine from cooking and from freezing. The reservoir has a cold fill line. Opening a hot radiator cap is how people get scalded. Color is not a spec — the chemistry on the jug is.
