I have a 2000 Hodan accord ex 4cy. at 99,590 miles, the transmission started to slip (rev between gears) honda replaced the transmission under a extended warranty program for defective trannys. Now about 30k miles later..same problem. This time started throwing codes..shift solenoid errors coard (cant remember the exact one). When the car is cold in the morning it will slip, but If I let it warm up for 5-10 minutes, the car drives fine. does this sound like solenoid problems or something else? If it is solenoids, how hard is it to replace and can anyone order the parts?

thanks,
