This may be a real dumb question but I remember a freind saying years ago that on TTS Datamaster he could see my transmission slipping under WOT. Is this the "slip rpm" topic under the transmission playback mode? If so how do I read it? I'll see RPM as 5002 (engine speed) and slip rpm as 683. Does that mean the trans is slipping? Just thought I'd ask what seems like an obvious question. Thanks for your time and help.
