urgent help needed - 2003 Odyssey tranny?

Need some wisdom from forum members. Just went through a car wash and immediately afterwards my tranny acted up. TCS and check engine light went on and the D for the gear selector display is blinking green. Immediately after pulling out of the car wash it seemed like the tranny did not want to shift into second gear. I pulled over waited a minute and it seemed to shift better but the warning lights are still on.

167,000 miles on original tranny...my guess is that it is shot but it seems so off that it happened right after the car wash. I changed the ATF fliud at every 7,000 miles so it is well taken care of.

Could it be that my tranny is shot or did something electrical get wet causing the problem? Honda dealership can't get me in till tomorrow.

Thanks
