| Vehicle transmission failed at 73,500 miles. vehicle just stopped in middle of highway while traveling at approx 45 miles per hour. subsequent rebuild by mechanic revealed that gm had installed incorrect valve body gaskets in the transmission, likely contributing to the premature failure. | |||

| My husband, my two children and i were all in our 2004 chevrolet avalanche k1500, headed to church on sunday morning, going down the street we live on. my husband, who was driving, turned on the cross street. all of a sudden, every one heard a big clunk, like some thing had dropped. the car would not move forward. my husband drove our vehicle backwards all the way home. it was parked for a few weeks, while we contacted aaa, the manufacturer, and local chevy dealerships to find out about repair and warranties. we believe this is a failure of the transmission. this vehicle has about 39000 miles, just over the written warranty, which is 36000. the manufacturer has not yet offered to pay for the repairs but advised us to take it in to the chevy dealership to confirm the diagnostics. the vehicle is currently be tested by a chevrolet dealership in redding, ca. the dealership has contacted the manufacturer to find out what they will do to repair the confirmed transmission problem. this is an expensive repair that has resulted in our loss of use of a vehicle that was within its normal expected use and represents a substantial financial burden. i have also contact the federal trade commission. i was please to know that the vehicle may still be within its implied warranty (first four years) and the right to revoke purchase may be an option if the manufacturer and dealership refuse to correct the problem at no cost to us. i am concerned that the problem, however, may be more widespread, and felt i should report this defect of the chevrolet avalanche 2004 k1500, for further investigation in case other owners have the same issue. *jb | |||

| (1) 2005 chevrolet avalanche 1500. 119,000 miles, 95% interstate. vehicle does not tow, go off road, or engage in other activities which would increase the stress on the drive train beyond normal wear and tear. transmission has received regular maintenance per the manufacturers recommendations. (2) part failed during merge onto highway from complete stop. failure resulted in a power loss to vehicle, making acceleration very difficult and maximizing vehicle speed at 35 mph. traffic behind vehicle had to significantly slow down to avoid accident. (3) dealer replaced torque converter and immediately shipped part off site before request for returned part. dealer claims customer abuse. *jb | |||

| May 2006 electronic switch replaced because 4 wheel drive was engaging without being activated. had been to dealership several times with problem and finally had them admit there was a problem. feb 2008 front wheel drive had to be replaced as it was a possibility that it could lock up while driving. out of warranty so i had to pay $1,300.00 in repairs. contacted gm exec offices and they investigated only to advise they could do nothing because the car warranty 35,000 miles had expired and car had 65,000 miles on it. i think the front end drive was damaged when the switch failed and it took time for it to fail. *tr | |||
