1999 GM Silverado 71,000 miles. New ventura 246 transfers case has developed a hole. The hole caused the loss of transfer case fluid under vehicle. Dealer and GM customer service content that is not there problem or fault and will not repair under defect of material or manufacturing. Dealer has also noted with GM customer service that the hole was a "puncture" indicating abuse. Local transmission shop (goodale transmissions. Columbus Ohio) indicate that this is a common problem with this transfer case. The holes are caused by a retaining spring (used to hold an internal pump? per service shop) break and rub on the inside of the case. Safety issues cased by this failure are possible fire when fluid is deposited on the exhaust system. Loss of rear brakes due to contamination by transfer case fluid. Possible loss of vehicle control if transfer case freezes due to lack of fluid. Repair cost for $900 to $3000 plus.

I own two (2) Chevrolet Silverado 4X4's - both have the same issue. Everyday the service 4X4 light comes on. I have taken both trucks to dealerships and they state that the computer is not indicating that light coming on so just ignore it. Just a computer glitch. Other transmission problems is loud clanking when placed in any gear from park.

Every time when taking off, something in the transmission or transfer case makes a loud audible noise. The truck makes a sudden jerk (when accelerator is applied) all is good during operation. When I stop again the whole process is repeated. Maybe the noise is coming from rear end possibly.

Without any indication, front end of vehicle locked up, causing consumer to lose control of vehicle. Dealer was contacted, and stated that subframe needed to be replaced. The front differential was torqued sideways and broken apart, causing the frame to have 2 breaks, this caused the front to lock up, also prior to this consumer complained of a delay between the forward and reverse, when a bump was felt when accelerating, consumer also heard a clunk noise, dealer drained and replaced the transfer case fluid twice. The engine sputters in 4 wheel low and there is a whine noise or pulley noise from the engine. The front seat arm rest fell off. The left front daytime lamp was full of water due to the assembly being improperly sealed at the factory. The brakes pulsated and pedal felt soft, dealer stated the right rear caliper was sticking and the front and rear rotors were corroded badly, causing the brake pads to wear. The electric brake was inoperable, dealer installed a new plug, the wiring harness was badly damaged. The power windows were inoperable. The left door creaks due to front door link being loose. Consumer was informed that he was supposed to sign a waiver because of the plow being placed onto the extended cab, this was because the installation was not recommended, however the consumer was never informed of this until after the installation and the problems with the vehicle.
