I tried doing the PCM reset today by unhooking my battery for 30 minutes and then following the steps outlined in the OM, but I'm wondering if it truly has relearned or if I need to leave it unhooked for much longer? I still had all my radio presets. Also, should my trip computer and everything be reset too? It definitely seemed to idle rougher as I first started it, so maybe it did. I want the transmission to relearn the shifting patterns since I bought my truck used and it had the previous owner's driving pattern learned.

 

Hey there. Just wondering if you ever got this sorted out. I'd like my truck to re-learn as well. Thanks!
