hey guys, let me start off by saying the truck has been great, not issues. put my dsp in about month or so ago. have not switched between tunes much, but have done it 2-3 times between a tow tune and a milage tune. with that said, drove it a bit friday night on miles tune, fine. saturday i had to go pick up my dads loader and bring it home to my house, needless to say i used my tow tune and tow haul mode. truck ran great shifted fine up and down. then towed the trailer back and it was fine. okay sunday mothers day, i drove the truck once in the morning to home depot, windows open and started feeling the down shifts, really pronounced, and then started hering them. it would clunk not bad but you could here "dunk" . it did this every down shift sunday. all day long. then last evening i was pulling up to a drive through while rolling up to the mic/speaker to place my order i put in nuetral, (timing rattle is quieter) and it felt like i slammed it into park, a huge clunk clank, crash, truck rattled like crazy. i slammed it back into drive and drove it home and parked it. please help. the upshifts are fine, no problems at all.
sorry for the long story but wanted to tell all.
