well, i put truck in shop today. estimated cost for new syncros is between 800 and 1500 dollars.... i`ll go to the shop thursday & take pictures of problem & post them

 

What shop are you at.

 

What lube are you using? I have been told that most failures of 5600s are due to the factory fluid and it not being changed often enough.

I use MTL for this reason-- so far so good; it's a LOT smoother, and that makes me feel better for the synchros.
