Ok, i have looked through alot of the threads but not finding exactly whats going on with mine. I have a 1999 odyssey ex with about 250,000 miles on it. Here are the problems that i am incurring. It shifts hard from 1st to 2nd and from 2nd to 3rd, also shifts hard when coming to a stop and shifting from 2nd down to 1st. Also when i shift from D to R it makes a horrible ratcheting sound followed by a loud clunk. It has started making a loud clunk sound when i am going in reverse also. I have had is scanned and no codes come up for the transmission. Strange thing is that once you get going it runs pretty smooth, a little bit of drag at highway speed but it seems fine then. So the main thing is the loud ratcheting sound with the clunk when putting it into reverse from drive, and also the loud clunking sound it makes when i put in revers and roll about 15 feet or so. Any suggestions, or has anyone else experienced this? Thanks for any help or suggestions.
