One problem related to transmission fluid leaking has been reported for the 2004 Chevrolet Suburban. The most recently reported issues are listed below.
2004 chevy Suburban 1500 4wd normal driving secondary roads. After stopping at a stop light the vehicle transmission shifted normally through second gear. Immediately and without warning the 2-3 shift resulted in severe slippage. There was no noise, no fluid leaks of any kind and no fluid contamination. The vehicle has been serviced by the selling dealer and has had the transmission fluid changed an two occasions by the dealer. A number of complaints about erratic transmission shifts and behaviors were noted each time the vehicle was brought in for routine maintenance and scheduled service. Each time the dealership was unable to replicate the problems complained about. Upon returning the vehicle to the selling dealer and authorizing removal and tear-down of the transmission we were told it was completely destroyed and needed complete rebuilding. The vehicle was phrased new, has had one driver, never towed anything, has had complete and timely service by the selling dealer. The mileage at the time of failure was 85,000. We had a gm extended warranty which expired at 75,000. The dealer won't cover it and after asking them to contact the chevy zone office to seek some support, I was told that was denied. When I asked for that denial in writing the dealership said that the zone official refused to do so. They are seeking between $2800 - $3,400. 00 for repair of the vehicle.
