hey guys. yesterday i made a 12hr trip and the g56 is spraying oil everywhere from somewhere. my complete underside from mid tranny back is soaked tailgate dont have a dry spot or the driverside of my cab side or bed. i pulled it apart checked the orange shift boot. it is damp on the top of the tranny but not to the extent of what is under my truck. it is literally still dripping today. i cant find any rips or cracks in the boot at all. and for the vibration this started before the leak in 6th gear 80 mph the gear shft vibrates bad. im to the point im wanting to do a nv5600 swap. let me know what you guys may think or something to check thanks guys

update i pulled the rubber boot stretching on it found a small pin hole and small cut about an 1/8'' long surely this thing cant push out this much oil???

 

my transfer case give me some trouble back in the winter. lost all my fluid and stretched the chain.

 

thats where i first thought my prob was the t case. but its wet at about mid trans back and 80 mph oil cant go forward know what i mean. but where was your tcase leaking at maybe that is my culprit im draining both fluids tomorrow to see which one was puking out for sure. thanks tony

 

a very common prob on these trucks are leaking thru the drive shaft. there is a plug that comes loose. lots of guys replace seals thinking that is the prob but a plug is loose in the drive shaft. i fixed mine with a card board cut out and silicone shoved in the drive shaft with a broom handle.

 

hmmm neither of my seals for my drivelines are leaking. i have never seen a leak this bad. my wife was following me in her tahoe and there is fluid on it. its that bad its crazy

 

that is a bad leak

 

and i still cant pin point it. but im going to drain the fluids tomorrow and see which is empty and see where i really need to search . i already have the shift boot off so im going to do the cv boot upgrade while im there.

 

that will tell the tale.

 

Any sugestions

 

have you checked the fluids yet
