Good day I have a 2007 5.7 charger and it is revving up when it shifts into 3rd gear, In standard mode, it is ok if I let the gas off for a bit longer otherwise it does the same thing. No engine codes. I did recently have to replace a good chunk of the cooling system. Got the dealer to check the transmission fluid and they said its all good. I am suspecting the speed sensor but with no codes am not sure. Any suggestions/help is appreciated. Thanks!
