also check the connection on your IAT. I've been told before that this will cause a incorrect reading to the computer that the air is really cold, and among other things, will stiffen up line pressure for firmer shifting.
Same symptoms exist on mine when using B&M Shift+ on setting 2. Hard shifts, and the whining noise.

-Blackjack- this is only true on the 4 bangers, seeign as how they dont have MAF sensors
the whinning is the sound of the transmission fluid being pumped at a higher pressure than it wants to/can handle. basically the ttransmission line pressure is too high and out of its desired threshhold.
to possibly fix your hard shifting problem. check your connections in your mass air flow sensor.
what could be happenuing is, the connection is making contact and then not making contact (engine vibration) on the wire that controls the transmission pressures.
if you are unsure if its your mass air flow sensor connection, it doesnt hurt to go to a GM dealership and ask for a MAF connection harness, which goes to a grand am 3.4, impala, monte carl, chevy venture, along with numerous others.
should run you around 30$ (it was 31$ for me)
hope that helped
no problem
