Rodger, although I have received a LOT of useful information on this Forum it is a weakness that we have to resort to descriptions instead of hands-on experience. I will try the stall experiment first chance I get but I am content that my 700R4 behaves almost exactly the way my 1998 Sunfire 4-speed and my 2008 Impala 4-speed behave. On the low gear only test I backed off in low gear at 3700 rpm because the test road is short and I was approaching a curve. Depending on how hard I press the pedal, the low to second shift may be at 2000 rpm, 2500 rpm or 3100 rpn where again I backed off on the 3100 rpm shift because I ran out of room before an impending curve. Ironically just around the bend there was a county patrol car so I slowed down just in time! I don't really understand the torque multiplication of the torque converter but it seems to work in the same way on all three of my GM driveline cars.
