The instructions do not call for emptying out the new ATF that goes in after the ARX treated fluid is removed through T-Tec. Why is that? With an engine the biggest part of the crud is supposedly removed in the rinse phase--and apparently really needs to be removed. Is there something about the cleaning method with transmissions that differs than the cleaning method with engines? I guess I have the same question as to the ARX application for power steering systems. I realize an engine will likely have more contamination than a transmission or power steering system, but wouldn't you still want to get rid of the rinse fluid after a relatively short interval?
