For the last day and a half I've been having trouble shifting into park. It's like I have to almost slam it into park (but I don't). Yesterday when I put it in park, it rolled, made two to three clicking sounds, and stopped. It rides ok in drive, but it's a b*tch to put it in park.

This morning I checked the transmission fluid and it was ok, so what could it be? Also, I just recently had this transmission, 4L80E, rebuilt.

 

I would check linkage ajustment first

Linkage adjustment

 

CHeck your linkage and make sure its going all the way into park at the transmission when you put the gear selector **** in park.
