09 5d hatch shifting problems
Cross post from the DIY - my 09 5DHB is down, transmission shifting problem.
Just got a call from AAMCO, and they told me the following. The speed sensor is fine, and is supplying the correct input to the speedometer. From there it sends a signal to the ECM, which controls the shift solenoids. It's losing voltage from the cluster to the ECM, and the car thinks I'm doing 35 mph when the speedometer reads 70. They said the transmission is perfectly fine otherwise. Has anyone had this happen?! This thing is my daily and I have a 150+ mile daily commute. Just buy another cluster and have a dealer reflash my keys?? Has anyone hooked a Modis up to verify those signals? |
