downshifts

My upshifts are always smooth, cold or warm, but until the car warms up, I have very rough downshifting when I increase the throttle, like the line pressure isn't dropping properly. Pnce the car is warm, it shifts fine. I have done 2 fluid drain and fills, added some Lucas Oil transmission fix...

Coming down a long hill in the mountains in cruise control my car exceeded the cruise setting (70) and the trans downshifted to slow it down. Surpised me! I did nothing! I cancelled the cruise so it would coast to above 70. Did anyone know this 2010 CRV would do this????
