Yes, at fast idle with the kick-down nearly all the way back. With the original spring, my line pressure was 85 to 90lbs. At 100lbs or so, there isn't as much spread in RPM between the 1-2 and the 2-3 shifts.

I had 125lbs or so for awhile but that caused the 1-2 shift to be several hundred RPM higher than the 2-3. Even with A&A's springs, the two shifts were too different for me. Besides, with the line pressure at 100lbs or so, the low speed shifts are much smoother. Which is nice running around town.

With 100lbs of line pressure the tranny seems to hold up okay. It has been there for a couple of years now.
