The transfer case wore a pine hole in the case from the oil pump spring lock not securing movement causing me to loose all oil from transfer case. This left me stranded when I could not shift into 4 wheel drive the could not get it to re- engage 2wheel drive. This could have possibly caused catastrophic loss of control had the transfer case locked up while driving at high speed on slick roads or if someone ran into me from sudden lock up of the drive train.

As with many other posts here, I too have had problems with both the instrument cluster(bad speedometer and gauge readings, "electrical") and also the transfer case with holes wearing through the case, "pump slap". Everything I have researched has LED to issues in both problems. I have since replaced both problems but still nothing back from gm. What a shame that these and all other issues can't be addressed by gm. I have not yet had a problem with the brakes, yet, but I tell you, it will be looked into. These both have happened under normal driving conditions.

2004 chevrolet silverado. Fire investigator writes in regards to vehicle dash fire *tgw the vehicle was heavily damaged by a fire which reportedly originated in the dash. The fire spread and consequently consumed the passenger compartment, then spread to the engine. The problem manifested while the driver was using the cigarette lighter. Prior to the fire, the transmission, alternator and a 15 amp fuse lighter fuse was replaced. The cigarette lighter was used frequently, plugging a 400 watt inverter which allowed the driver to use his computer.

About a second later, white smoke starting coming from the dash. There were no cigarettes in the ash tray. The smoke started to increase and the consumer identified the problem as an electrical insulation smoke odor. The smoke was coming from the back of the dash; there was no smoke coming from the engine compartment or the hood at that time. It was in the fire investigator's opinion, that the results of the examination lead to a conclusion that on a more probable than not basis, an electrical anomaly at the dash area and in the vicinity of the cigarette lighter ignited nearby combustibles and the fire spread into the passenger compartment.

2004 chevy silverado hd 2500 diesel--transfer case wearing from inside out I took my truck in to have service work done on it, and found out from the jasper transmission company, that they are doing a large number of chevy transfer cases because they weren't shimmied right from the factory, causing the gears in the transfer case to eat through the bottom of the housing on the transfer case itself. This then results in the transfer case fluid to leak out, and causes the gear box to come apart inside the transfer case. The chevy dealer that I took my truck to never even mentioned this to me, and was very evasive about the whole issue. I will never buy another gmc (gov't. Motors corp.) car or truck again!!

Transfer case develops hole from pump inside on my 2004 chevy 2500 hd duramax. Sounds like this is a very common problem with gm owners with this type of transfer case. Its being called the infamous pump rub. Sounds like gm is ignoring this problem. This should not be happening on vehicles this new with little miles on them.
