Four problems related to transfer case have been reported for the 1999 Chevrolet Silverado. The most recently reported issues are listed below.
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.
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.
Truck has been at dealer for repair total of 35 days before 1st anniv. Of ownership with over 20 separate problems, 5 of which are unresolved to this date. Vehicle is at dealer now for final repair before TN lemon law can be implemented. Worst and current problems are front end alignment (pulls to right), front brake squealing (pads replaced twice, rotors turned once), rear end vibration at any speed and clanking sound over bumps(all 4 tires, both rear leaf spring stacks, all 4 shocks replaced. One shock had broken shaft) , engine backfires & knocks at startup (dealer reprogrammed comp. W/no results except to improve power, but accel. Pedal sticks now!), trans. Slips from dead stop for few seconds about once per week, 4wd transfer case slipped in low in deep snow (replaced fluid and did reprogram. Results??), ext. Cab pop out windows replaced due to poor fit (one exploded upon removal & dealer had to repaint side of truck. New ones are no better than originals!), rear seat missing rubber mounts(dealer replaced, but now seat makes popping noise due to rear cab wall flexing!), drive shaft makes loud clanking sound when shifting from park(dealer says this normal!). Problems repaired: rear brake line loose & in harms way(missing mount replaced), steering box loose and steering column rattled and loose around any turns(box tightened and column shaft replaced), drivers side window switch sticking in down posit. (switch replaced), all door weatherstrips and drip rail molding loose (replaced all), rear license plate light broken and replaced, door lock levers fell out of both doors(replaced both). Lemon, lemon,lemon!!!!!!!!!!( dot number: ).
The vehicle has the automatic four wheel drive, once it was applied the brakes stopped working. The vehicle was serviced and the problem still continued.
