This pump leak repair will eventually be paid for by GM. Here is how this works. Years...perhaps months from now, a lawsuit will occur over the tens of thousands of people who will have to have this repair done on their transfer cases, and GM will admit to this issue in court, and be forced to pay for the damages it caused. They already know this, but will stall paying until they get sued.

They did this on the 3.8 liter GM engine with plastic intake manifold, but it came years afterwords, and guess what??? By then the number of people who saved their receipts had long since lost the receipts or canceled checks which they used to pay for the repair.

SO DOCUMENT YOUR REPAIRS FILE THE RECEIPTS AND WAIT FOR THE NOTICE FROM LAWYERS WHO WILL CONTACT YOU VIA YOUR VIN NUMBER.

I know this sucks, but at least you will get most of the money back someday....if you took care to save the repair receipt and date time it was repaired, and saved the cancelled check or credit card showing who and for what it was for.

This is the new corporate game played by all the manufacturers. If you deny that it is happening until they get a good class action suit against them then years from now they pay, but know that it will be so far out that most people won't bother or won't have the evidence that they had to have it done.

Be smart and be prepared. I know I learned....from the 3.8 liter engine deal and I will never discard a receipt for this type of repair again.
