Id say that too but I had the same problem but for 1st gear. Whenever it gets warm, it would gind in 1st no matter what. I just went to a GM dealer and bought some GM Syncroshift and changed the tranny fluid. It has worked so far and that was 3 months ago. I'd say try that or what the guy above me said.

Or, if you're trying this route, instead of paying GM's price for it, buy Pennzoil Synchromesh at Auto Zone for $4 a quart.
