I have a 2002 2500HD w/Duramax Diesel. I noticed about 2 years ago oil leaking from underneath the TC. I cleaned the area and noticed a hole that the oil was coming from. My local dealer offered no help. I had to patch with JD weld. I have to go and reapply it about every 6 months. GM should recall and replace at no cost to the customer.

I have a question. Does this clip failure accompany a whine? I have no leaks, but one hell of a whine from my transfer case while driving lower RPMs, seems to let up at highway speeds. It is a 2000 Silverado, 4x4 extended cab, 5.3, 164,000 miles, and been kept well maintained by me.

2003 Silverado 2500HD. 4WD wouldn't engage. Pin hole, no fluid. I'm a 6 time GM product owner, but no more for me.

I have an 03 Silverado 5.3 Z-71. I too have been a loyal GM customer for years, but no longer. I am cured of GM and will never buy anything from them again.

I currently own two GM products and can't believe that they both have SO many issues. The leaky transfer case problem is just one more thing that compounds the long list of problems. Wait until you have the intake gaskets go out because they are flawed from the factory (if your truck has over 80,000 miles you're on your own to the tune of $800). Then your gauge cluster quits working (also a defect that GM knows about but won't stand behind (another $700).

There are better vehicle options out there and I'll be taking my future business elsewhere.

I am also having a problem with my 2003 2500 Silverado. The mileage is high and would gladly fix it at my own expense if there was a fix that would work. There seems to be a wide range in cost for a new TC; the one I priced was over $2000. GM should do something to help; it is clearly a defective part.

2004 GMC EXT CAB Z71, 85,000 miles, and I too have a leaking transfer that GM knew was at fault. I also have a drive shaft that sounds like it is going to knock through the fire wall at any time, that GM is very much aware of the issue.

Gaskets that I have repaired on the coolant reservoir that is common for GM trucks!

I don’t understand the thinking behind companies, nor the people that hold them accountable! If I had a company selling fault equipment or a bad product, then they would close me down or make me replace the product! Then there would still even be a risk of going to prison for selling something that I knew was bad!

To tell you the truth, my dad has a Ford F250 that has been in the shop more than in the driveway as well!

These people need to be held accountable for their products they are selling us! I am tired of throwing hard earned money out the window for JUNK!

I have a 2003 Chevy Silverado LS with 112,000 miles, and am now adding myself to the leaky transfer case issue that obviously several folks have had an issue with.

I drove FORD for several years, and always ran into several mechanical issues. This was my first Chevy I have ever purchased, and now I am running into the these horrible problems I had when I owned a FORD. Guess in this day and age, it's better to pay a few thousand and drive a junker; then when something goes bad, it's easier to just buy another junker.

A tractor trailer can run 24 hours a day and operate 7 days a week, and go a million miles, but we can't make a vehicle that runs over 100,000 without having major issues. The Silverado is a very nice truck with lots of room, however I am very disappointed in its quality.

I have an '03 Silverado and replaced the transfer case two years ago due to fluid leaking. It cost me $1600 at the dealership. Now exactly two years later it is leaking again. Too many other issues with this truck as well.

I'm done with Chevy.

The pin hole in transfer case strikes again. I bought a 2002 Silverado 4W a year ago from a Chevy dealer a year ago. 2 weeks after I bought it, the water pump went out, cost me almost $600 to replace it. About 5 months later, the starter goes out, 2 months later, the fuel pump went out. Now 11 months after I bought this truck, I have to pay $1400 to replace the transfer case because of a known defect (hole(s) in the case).

I know of 3 cases; 2003 Suburban, 2004 Z71, 2003 1500. Small pin hole in tail housing. Repaired with JB Weld after the third one. GM had to know of this problem. They denied any problem. So far 2 have held, 1 didn't; went back, had a bigger hole, it had broken through the JB Weld, looks like JB Weld is not a fix.

2001 Chevy with 77,000 miles leaking at the transfer case. Wife's 2007 Suburban transmission quit at 16,000 miles and transfer case leaked at 80,000 miles. What to buy?

2002 2500 HD - pin hole leak in transfer case at 94000 miles cost me nearly $3000 dollars. Asked the GM dealer if this was a common problem. He said he had never heard of it happening. I have 144,000 miles, and the transfer case is bad again. The truck has also had the automatic transmission rebuilt twice. Not to mention the valve spring that broke and sent the valve into the piston at 40,000 miles. GM should take care of their problem. I have owned GM trucks for 30 years. I just bought a Dodge.

Well, I feel lucky that my 1999 Tahoe with 154,000 just started leaking from the crack in the case. After hearing all of the 2003-2008 stories, I guess I was lucky to have lasted this long. I think JB Weld will solve my problem, as the crack is very small. I might later go with the Up-grade kit from Merchant Automotive.

I am now part of the "pinhole club", not by choice! 2003 Silverado HD with 105,000 miles. It will be costing me around $2,000 to fix. I was told GM is still selling the transfer cases with the issue (pump/pinhole) not resolved. Unless GM makes it right when I call customer service, it will be the last GM I own!

My husband put his comment on here about our truck breaking down, and we have decided to send a letter to GM in Detroit, Michigan about the complaints, including our truck. We sent it so somebody would have to sign for it, and we are hoping to hear something back from them.

20th Dec 2010, 21:56

I have a 2003 Suburban 1500. It also had a leak about 2 years ago, and I had it welded. Found out today it has another pin hole leak in rear housing. I will try and use JB weld to temporary fix, and look at finding another TC or trade in for another brand.
