[QUOTE="primetime1267, post: 348835, member: 5293"] Ohh hell yeah brotha, I just had this problem last week.. I just installed a BTS valvebody and his new tunes and 2 days later my trans started acting up.. Threw the same codes as you and I fiddled around with everything triple checking things.. Then I checked my scangauge2 voltage, it was around 11.9-12.2.. Went to advanced and had them to do a load test and check alternator... BAD alternator,"excessive ripplings" tossed in a new one, 14.1 volts right off the get go. I even pulled out a fairly new Motocraft alternator.. My trans shifts sooo much better now, I thought I was going to have to rebuild the trans, now I can wait for a bit... Time to turn up the tunes and see what happens, LOL. ohh yeah, checks those grounding cables as well, I had one that the bolt was only in 2 threads.. [/QUOTE]
