Hey guys,

So I need to know why my gt is shifting late and overall feels weaker after I unplugged the battery. I took it to the dealership three times now and first they said some circuits were bad and those were replaced, nothing though, no fix.
Second time I took it they said something about solenoid and I drove it and the car felt great but later went back to its antics. The third time I took it they said nothing came up wrong, the car showed no alerts and is operating as designed. Still though I bought this car now and I can definitely tell a difference in its performance after the battery unplug. Thoughts please, thanks in advance.
