Trying to help out my neighbor here.
2007 Charger with a 2.7L. 100k+ Miles on the body/transmission.
"If I drive very carefully I can get it up to highway speed. If I romp on it, or push it too hard to pass etc, seems to go into limp mode. Sometimes the speedo will follow the tach. Like it's hanging in gears."
How should we start troubleshooting?
Does anyone know if the "Key Dance" will display transmission codes? It appears to show Power-train codes, which I assume would cover the transmission codes, but are there Chrysler specific codes that do not present themselves in the DTC P-Codes, requiring different tools/protocols to read?
I am not sure I can read transmission codes with my BAFX and TorquePro?
