I'm not posting this thread to sell this piece so please don't delete it as I am not associated with merchant automotiive in any way,I'm posting this to save fellow duramax owners from a 1500-2200$ repair bill from running their t-cases out of oil. On a low mile vehicle the pump piece could be installed before transfer case is worn thru or has much wear with common sense and average mechaic skills,on a higher mileage vehicle plan on changing the rear t-case 1/2 ( about 300-350$)when installing the pump piece,even though it hasn't worn completely thru it will still be junk. Anyone in Mi in my area that needs this done can call the number on my signature if they need a installer,Smitty

Wrink,my computer room has about 400 sets of beads hanging on the wall next to my key west mile zero marker and other boating "trophys":evilb: . My mom was up here from florida last year and asked what all the beads were from,I said we go to alot of boating "festivals" where they hand them out!!!:D
Back to the t-case thread-the vendor I'm getting the new t-case from for the customer insist on having me fill it with gm synchromesh fluid,it won't stop the pump from rubbing thru but it supposedly works better than atf overall,Smitty

thank's for the info

I work in used auto parts, and I agree. These things are garbage and used ones will still run you a grand if you can find one. Ranks right up there with the piston slap GM wont acknowledge on the LS based motors.

I had to replace mine at a little over 100K. They said the front shaft was warped and caused the seal to throw all the fluid. I thought that was strange since i do not use 4 wheel except at the ramp. $3500 later I was back on the roads.

Last oil change dealer says slight tranfercase leak. 144k mi, should I have it looked at?

Depends what kind of leak,a slight leak around rear seal isn't un-common when a little rust rubs seal/slop in driveshaft yoke. On the other hand if the actual case is wet and it isn't from the rear seal then you should definately fix it before you hurt it and have to spend big bucks for a complete unit to replace it,Smitty
