i have a 2005 ram 3500 with a nv5600. I noticed a leak today somewhere high. has any one had this leak and is it repairable in the truck? thank you for any help.

 

most likely the boot on top of the shifter. i have the g56 replacement part # but not the nv5600. someone should chime in with it. go back with one quart over full with gorilla juice for a total of 6 quarts. pour the last quart in the top when replacing boot. it is a 17 mm for the fill plug

 

pulled out the consol and noticed the gasket leaking pulled it out resealed and reinstalled hope that was the fix .

 

Pretty common. I just reseal mine with a bead of black RTV...
