,,,drains almost all the ATF from the system, including the torque convertor. That's the point of the recommendation of the "T-Tec" procedure: most transmission services on many cars & trucks just drop the pan and clean the screen/replace the filter, leaving quite a bit of old ATF in the system. You want to get as much out as you can.

I personally have not used Auto-Rx in my transmissions (yet!) as I just had them serviced recently (<10K miles) and have experienced no problems (Well, the SVX tranny was replaced under warranty 6 years ago, but that's another story...).

If you remember that Auto-Rx is for cleaning, you might also consider investigating a product called LubeGuard (Red) for additional AT lubrication. This is one additive that many feel provides measurable benefits. It is reportedly used extensively in the tranny rebuild industry, and for some time.



Regards!
