| Check engine light illuminated after 300 miles travel. hard shift from first to second (felt like transmission dropped from vehicle. this first occurred six months after purchase of 2003 chevrolet suburban (new). dealer re-programmed transmission control module. same problem on return trip four days later, and six more times in the past 2 1/2 years. four separate gm dealers, in two states, have attempted fix via: 1. re-program tcm, 2. replace transmission solenoid, 3. replace transmission valve body and re-program tcm. still not fixed.*jb | |||

| I purchased a new 2003 chevrolet suburban in december of 2003. on may 13, 2005, the transmission began to fail rapidly. the automatic transmission will not easily shift into second gear and reverse gear does not function at all. the car came with a 3 year 36,000 mile power train warranty and i have put 48,000 miles on it in the eighteen months that i've owned it. 98% of the miles on the odometer are highway miles. i have towed a boat exactly 4 times. i took the car to a chevrolet dealer who indicated that the transmission needed to be replaced at a cost of $2452.00 chevrolet has offered to pay for the parts & wants me to pay for the labor-$900.00 there are two technical safety bulletins relating to this problem- #030730028 drivetrain clunks when stopping and 00822b, no second & fouth gears and no reverse | |||

| Regular harsh engagement on my 2003 chevrolet tahoe transmission. 1) had a huge clunk when having to suddently stop on one occasion - sounded like the transmission was going to drop/bam. 2) on an unpredictable basis the transmission harshly engages when going shifting at the slower spds. 3) brought to service dealor and they acknowledge problem during a test drive that needs to be ck'd out. they said they fixed. 4) problem was worse when car was received back (have no idea if car will ever bam/clunk/wham/drop again as i normally don't suddenly stop but whatever that was it certainly wasn't good for the transmission). i reported the frequency of the harsh engagements actually were more often and they then changed there tune citing a service bulletin saying it's normal . 5) now 15,000 miles later of harsh engagements i'm sensing some slippage and those harsh engagements are now harsher. i'm very disappointed in the performance of my tahoe and am very concerned of the future of the transmission in that gm & belzers acknowledge the problem then said gm says not to do anything. car still runs but it very annoying when driving in the cities stop and go traffice...a clunk clunk here and a clunk clunk there here a clunk there a clunk. this is absolutely ridiculous!*ak | |||

| Consumer stated that his 2 yr old son was able to pull his vehicle out of park without stepping on the brakes. he stated that the child was in the vehicle and was apparently playing with the gear shifter. he then moved the shift level causing the vehicle to roll backward hitting a pole and bending his front passenger side door. he stated he does not think this vehicle has a shift interlock, which will not allow the gear shifter to be moved without stepping on the brakes first. he stated he took the vehicle to the dealer and they did not know this either. the consumer stated the interlock only works when the key is in the ignition to drive. *jb | |||
