I attached the diagnostic info for this code. Also, I attached the repair procedure for the input speed sensor. It looks like this is on the valve body inside the transmission pan.
However, this code clearly is the cause of your shifting issues. The input speed sensor is used by the TCM to determine shift points and line pressure. If this is not accurate then it will cause shifting issues. However, before you just disassemble the transmission to replace this, I would run through the diagram because it could be the TCM itself.
Please let me know if you need more information but this test process is what you need to determine what repair is needed. Thanks
