2003 chevy Trailblazer. Transfer case needed to be replaced in 2006, @ 32,000 miles under warranty. Transfer case needs to be replaced again 2009 @ 66,000 miles, warranty period over ,now its $2200. 00 out my pocket. After researching this is a well known problem with these transfer cases. The bearing installed can not handle it. Apparently gm has recently updated the bearing. Gm will not recall these transfer cases. Other gm vehicles have related issues with the transfer case.

Failure Date: 01/14/2008

The vehicle transfer case has failed twice. The first failure occurred at 33,377 miles. The dealer repaired the vehicle under the vehicle original warranty. The second failure occurred with 43,971 miles. (miles per each transfer case)the vehicle was idling rough and in 4wd. I selected the awd mode and the vehicle made a clunking sound but stopped idling rough. When I tried to put it back in 4wd it would not go into the 4wd mode. When I returned home I tried to put the vehicle in 4 low and it went into 4 low but would not come out of 4 low. The servicing dealer and gm claim the tc failure is because we live in a northern state and therefore use the awd and 4wd more than other regions. I spoke with another dealer and they claim gm is aware of this problem, but cannot fix it. The second dealer said they could repair the vehicle, but assured me that the tc would fail again. Both dealer said they see these Trailblazer tc failing all winter long. There were about 4 to 5 Trailblazers in the service dept (not including ours) with broken transfer cases.

Vehicle was bought brand new from gm dealer on oct 31, 2002. Vehicle has 71,770 miles on it. Was driving less than 6 miles to work in the morning and gave it gas and felt something break. Forward gears had little power and had a high wining sound to them. Had no reverse gear. Had to have vehicle towed. Dealer diagnosed it over the phone. Dealer opened the transmission and found the reaction sun shell in the transmission stripped. Dealer stated they have repaired these before, it was common occurrence in gm vehicles due to poor quality of metal used in transmission. Dealer had to tear apart transmission, remove drive shafts, transfer case, install new sun shell, related seals, and bearings.

car   Transfer Case problem 6
Failure Date: 07/01/2006

Purchased 2003 Trailblazer in October 2003. Had problems shifting into 4wd in winter 2003-04. When switching into and 4-wd, lights would flash and it would remain in 2-wd. Service 4wd light came on soon after. Brought it to the dealer who could not replicate problem. This happened later the same year and also the following year, each time the dealer could not find a problem. This past weekend while on vacation, a parking valet for some odd reason, switched the car into 4-wd low. Car will not come out of 4-wd low. Had to leave at dealer 150 miles from home and rent a car to get home. I am waiting until after the 4th of July holiday for them to look at car and figure out problem.

Upon cranking the vehicle the service 4wd indicator light in the gauge console area lights up, while at the same time the selector light for which setting the transfer case is in goes out. The selector switch is in the 2wd setting and there will be no amber light indicating it. You can switch the selector to awd or 4wd or back to 2wd and no indicator light. Sometimes it can me "fixed" by turning the vehicle off and restarting the engine.
