The transmission hunting problem was solved with the apps noise isolator (i think that's the correct terminology. I got mine from BD but there are a few other options. The Suncoast and ATS solutions seem to work for others. The one from BD took all of 2 minutes to install and i haven't had a problem since. The actual apps you can get from geno's or Blue Chip. That repair is very simple as well and should eliminate your problem. Start with the APPS noise filter and go from there.
