A transmission fluid flush runs $180 to $350 at most shops. A drain-and-fill is closer to $120 to $200 and is what most newer cars actually call for. Doing this on a neglected high-mileage transmission can do more harm than good.
Most drivers pay $200 to $280 for a full ATF exchange at an independent shop.
OEM-spec ATF (Honda DW-1, Dexron VI, Mercon ULV) costs more.
6-9 quarts for most cars, 12-15 quarts for trucks.
A full exchange machine costs 40-60% more.
Many transmissions need pan dropped to replace filter, adds $60-$120.
Replaced when pan is dropped, $20-$60.
Dealerships and AAMCO charge significantly more.

Every 30,000-60,000 miles for severe service, every 60,000-100,000 miles for normal driving. "Lifetime" fluid in ZF 8HP and others still benefits from service every 60K.
Possibly. If the transmission already slips, a flush can dislodge debris and make it worse. On a well-maintained transmission, regular service helps it last longer.
Drain-and-fill replaces 30-50% of the fluid through the pan. A flush uses a machine to push new fluid in while old fluid pumps out, replacing 90%+.
No - modern transmissions need their exact specification (Honda DW-1, Mercon ULV, Mopar ZF 8&9HP, etc.). Wrong fluid causes shift problems within weeks.
They need specific fluid changes, not flushes. CVT fluid every 30-60K miles, DCT every 40-60K. Use only the exact OEM fluid.
Lifetime means "the life of the transmission" - which the manufacturer expects to be 100,000-150,000 miles. To keep a car longer than that, service the fluid.
