Howdy All!

I have a 2003 Wrangler Freedom Edition, and have a re-occuring automatic transmission/PCM issue. A couple of years ago, a hard down shift into 1st gear occured. If the over-drive was shut off, the down shift was normal. A reptuable transmission shop performed diagnostics, and determined that there was no mechanical issue, and that it was an electronic problem. The PCM was re-flashed, and normal shifting returned. This lasted for over a year, and the same issue has returned twice, and twice more re-flashing corrected the problem. Today, it has returned again...I would assume a re-flash is in order, however I'd like to find out why this keeps returning. Anyone have this issue before, and found a solution. Thanks!

Try leaving your positive battery cable off overnight. If it's an issue in volatile storage, that'll clear it.

Thanks for the replies.......I'm having some diagnostics done in the morning, I'll update the findings as soon as I have some new info.

Thanks again!
