And I'm pretty sure they always use Maxlife. But you can ask and check it out. I know mine does, I saw them filling their machine with gallon jugs of it.
Oh, and ask what technique they use. My Valvoline shop used to hook a line to the transmission cool and use that method of flushing. Now they basically stick a tube down the fill hole, suck out fluid. Then start up the vehicle and add the missing volume with fresh. Let it run for a bit, shift the car/truck through the gears, and suck out the torque converter again. Then re-fill. They repeat several times, thus changing out a big portion of the ATF. At least they claim it does. My ATF is always nice and red and clear when they are done.
And I interrupt them before they top it off, and drop in a bottle or two of Red Lubegard.
Does anyone think this method of removing/replacing the ATF in the torque converter is effective or not effective? Does it make sense or are they really not getting most of the old fluid out?
Only a very few cars have a drain for the torque converter so I do not think they do anything with the torque converter. They are just doing multiple drain and fills (suck-out and fills). The percentage of new ATF depends upon the ratio of pan to total capacity. Most are around 1/3. What about the filter.
The quick lube places do not want to drop the pan. So they either use a flush machine or multiple drain & fills,
