Speedometer and tachometer quit working and fuel gauge stuck in middle position

Replaced the VSS sensor thinking it would fix the problem. However, it is still the same and having problem shifting also. I was told a transmission pan gasket and filter change. Could help the issue. How would that do anything for gauges?There were no blown fuses I could see. Ever had these issues fellow humans? Could it be the connector for VSS? Also my scan wont show codes it has kinda got me. Please help me. Thanks all
