Probably depends on the problem/symptom.
Brake band adjustment compensates for wear and the inability of the band to provide full braking of the planetary gear drum.
Wear of a brake clutch pack plates is rare -- one reason why the change was made. A weak seal on the clutch piston could cause delays, or lack of lock-up, or a malfunctioning shift solenoid or accumulator could lead to a lack of "braking" similar to a brake band that isn't clamping down sufficiently. If this happens, and a multiple change of ATF doesn't help, it does mean some more complicated repair work.
