Manual trans won’t shift in or out of gear with truck running on my 07 Dodge Ram 1500

Sounds like a clutch problem. Have you checked the fluid level in your hydraulic clutch reservoir?

Do the gears "grind" when you're trying to shift or just won't move?

The fluid is full if you turn motor off it goes in gear just catchy not grinding when in gear it pulls fine a couple people told me to replace the slay cylinder and master cylinder

have you checked the lube level in the tranny? If it's low, the shifting can get "problematic". Also, if you recently replaced the tranny oil, what kind n amount dijya use?
