Enter the data(include tire diameter and gearing info) into your calculator to get the converter slip #'s. Use a very flat road surface and windy days aren't the best if you want to be accurate.

I was using the trap speed for my overall and TC slip calcs. I was just trying to get a ballpark on the convertor slip @ highway speed as to whether it decreases to zero with minimal load or �3% or is it the same as at trap speed.

Get on the highway and use your watch and the mile markers.... 60 seconds per mile is 60 mph then check the rpm then do your calculations.... but under light loads the stall goes way down(less torque), thats why you can still use a high stall conv on the street
