After you rule all those out (which I'd bet is where your issue is) would be to crack into the trans.
Try the easy stuff but be prepared to tear into it and get down and dirty if the problem remains.
Hard shifting symptoms is also caused from worn shift selector, worn shift fork cogs and/or bent shift forks. Also never rule out worn/damaged syncros.
Lower mileage usually equates to BB_r/t's solution and higher mileage is usually worn/damaged parts internal.
At 70k I performed the entire oem clutch system replacement but still could not shift for shit stopped. Once I got it into gear and moving shifting was ok. Eventually swapped in a trans with 16k and it's perfect shifting again. Old trans still sits waiting for tearing down, but compared to replacement it's shift fork cogs and shift selector are severly worn...
