Help me Diagnose
 

Hey guys I've had my 4Runner for alil over a month now and I love it. It drives great with the exception of a couple issues. The problem is when I'm coming to a dead stop it feels like the transmission is hesitating gearing down to first. I'll be stopped and I'll let my foot off the brakes a little bit and you can feel the vehicle sorta jolt but it does not make a noise just feels like it shifted down. It just seems like it should already have shifted before I'm completely stopped. Also and I duno if its related is I get a loud clunk and jolt when I'm stopped and I put it into drive. Does anyone know what my problem could be?

More info needed...Is it 4wd? If so, grease ALL of your zerks

Yes it is 4wd 2000 Limited Auto w 91K miles ..............Is that what could be causing these symptoms??
