I got my throttle body up graded to 71mm and the mechanic who replaced the throttle bodies didn't disconnect the battery while removing the old throttle body and my car is tuned with a device which I'm using with no issues for more than a year, so when I got he I updated the car again with the device and drove the car to a highway and noticed the car wasn't switching gears the rpm kept incearsing to 5000rpm to 7000rpm at a speed of 75mph ( a jet scream noise came when at high rpms) for more than a mile. Then I stopped several times and used the tuning device with different settings, on 1 attempt I switched the car off and walked off locking the car and then when I drove the car was switching gears fine with no issues, I guess since the mechanic didn't disconnect the battery so the ECU developed a glitch and my question is that is it possible I damaged the transmission?
Will I have to get a new transmission after a while?
My car is a Dodge Charger 3.5 v6 2009
No error light came on and no over heating occurred what so ever
have the same problem?
