.....THANKS Mooneye, THANKS Tech, ok I'll check it out tomorrow. I forgot to mention that I have a trans brake so I guess the best way is the True Stall way??? If so I've noticed that the most my car will rev up with the trans brake on is around 2800 RPM. So this must be where my converter is stalling at??? I thought something was broken cuz it wouldn't rev any higher....... But tomorrow I'll 'play around' with the three different ways ..... THANKS again, this site is such a valuable help. Bill
