They also have you start the car, using the transmission pump to pump the fluid in the normal direction. Therefore the horror stories about backflushing and loosening crud are bunk. My friend has used NTB, and they used the solvent first then new fluid. What that did was eat away his old brittle transmission cooler lines and cause them to drip a little. Therefore, I wouldn't use a solvent system, just a simple fluid flush.
Wonder if they ran the car through the gears, which is needed to ensure all the old ATF is out from all the paths.
Not a good idea to run the tranny through the gears while flushing it. If it's a dodge, the transmission lines won't flow unless it's in neutral. Been there, done that. The gears are ran through after the flush, to ensure tranny fluid is completely circulated. Then we can get an accurate level on the dipstick.
