1992 Buick Roadmaster Transmission and drivetrain Problems

“Consumer stated without prior warning, the vehicle hesitates when shifting gears. . Consumer stated the driver wheel fell broke off due to the nuts and bolts had broken off, the brakes went out, the vehicle would not go into reverse, the thermostat went out, passenger window would not roll down, turn siganl was inoperative, windshield was replaced, and the upper ball joints were replaced.”

“When vehicle was either in drive or reverse and making a turn, could hear a clunking noise. This problem occurred at low speeds. Have taken vehicle to dealer at least 4 or more times. Each time mechanic indicated non-slip differential was causing clunking noise. Mechanic drained differential, and replaced it with an additive to help release better.but, problem still exists. Dealer has: replaced the serpentine belt, serviced the rear differential twice, and drained and refilled fluids, problem still remains.”

“When vehicle reached 46 thousand miles transmission would not change gears. Could cause an accident. At 36000 miles, dealer changed filter and fluid, 10000 miles later, it completely failed and was replaced.”
