"Basically, you need to shift sooner and/or harder. Lengthen the control pressure cable for the first, run the modulator in a turn for the second."
I mentioned that my tranny was shifting a little "hard", and my mechanic did adjustment #1.
I didn't know it was possible to do adjustment #2.
I will see if my mechanic can reverse adjustment #1 and instead do the adjustment #2 to try to ease the "harshness" of the shift.
