I own a 2010 RT ...I've recently put a refurbished ECM/PCM/ECU on the car this fixed my original problem of it not dying nearly every time I put it in R or D. However, it didn't register to shift into OD and of course kept the RPMs up while driving 65-80mph. The mechanic shop was an ordeal and so I let them go and ordered a new ECM/PCM/ECU (figured it was faulty and wasn't programmed correctly) get it put in and as it turns out this is not correcting the problem. So, I need to know what can cause the car not to shift into OD of it's not the ECM/PCM/ECU.

Is the computer throwing any codes? Have you serviced the transmission(oil and filter change)?

No, no codes. Yes, car has had consistent oil changes and a recent tune up about 3months ago.

Not engine oil change, transmission oil and filter change. Important, don't do a transmission flush, it may cause more harm than good. Just pull the transmission pan off, drain oil and change filter.
