Why is Car not shifting out of second

Hello, the code relates to a concern with shift solenoid B. I can tell you that my experience (working at a Honda dealership service operation) is that internal transmission concern codes are not generally repairable. There is a diagnostic troubleshooting flowchart, and you could certainly obtain a workshop manual, a good diagnostic tool and a digital voltmeter / ohmmeter (DVOM) and perform the testing. In the end, I think you're going to find transmission replacement I necessary. www.repairpal.com/repair-shops
