Ive have had this honda since it had 170K miles on it... It has over 250K miles on it now i think near 8 years... When I bought it years ago i figured the transmission had some wear or perhaps it was on borrowed time b/c if shifted funny from 1st gear to 2nd gear.. Once in a while it would sorta bang into 2nd gear..If I drove it very easy and took off from a stop very slow it would sorta float into 2nd gear and wouldnt do that horrible bang. Now many things improved it like new trans mounts / engine mounts ECT.. Also LubeGaurd Shudder fix. That seemed to help it also.. Finally i started to change the Dual Liner solenoid and that really didn't help but I had a code pop up for the dual liner solenoid so I changed it.. ** DENSO ** The D light was blinking and as soon as I changed the dual liner selenoid the flashing Green D light stopped... I even changed the Torque Converter lock out solenoid.
Well I finally figured it out ** Becasue I was out of things to change **... Honda has 2nd gear and 3 gear Transmission Pressure Switches part # 28600-P7Z-003 and or 28600-P7Z-013 .. So I got real Honda ones from work via World Pac and the trans takes 2 but I only changed the 2nd gear switch and as soon as I drove the car it was like a new transmission.. I was shocked.. I then figued since I have both I might as well change them both so I did the 3rd gear one also..
Its unreal how awesome this transmission shifts now.... So if anyone has a Honda Transmission that sorta bangs into 2nd gear please do yourself a favor and buy

They look like the picture below.. Now becareful I seen many knock offs on ebay and amazon.. The non oem have glue on them and the Genuine Honda even the Intermotor was made in Japan and was the exact same thing as the one in the Honda bag...
