And some people warn against performing a flush on a transmission using old, dirty fluid. The flushing procedure may cause some fluid to move in the opposite direction of normal flow due to eddy currents, which may increase the risk of dislodging debris and causing it to settle somewhere it shouldn't.

Similarly, you may ask, are transmission flushes worth it?
If you do a lot of mountain driving or heave towing, then a flush would be necessary. Under normal driving conditions, a flush is NOT necessary at 46K miles. The shops make money on flushes, that's why they recommend them. Most transmissions are good for 100,000 miles before requiring maintenance.
One may also ask, can changing my transmission fluid be bad? Changing the fluid and filter is never a bad idea, as long as you use the correct parts, as there are many types of trans fluid - all with different characteristics.
Subsequently, one may also ask, why is a transmission flush bad?
