Automatic Transmission Problems of GMC Suburban

Contact owns a 2002 GMC Suburban. While driving and changing gears, and when putting it in reverse it sounds like the engine is falling out. While changing gears its like a big thud. When changing from park to reverse it sounds like it is coming apart. When turning the car into neutral red light stays on, and that has never happened before. The contact will take the vehicle to the dealership to be checked. Also, the contact smelled a burning odor.

1998 Suburban w/ 4l60e transmission, shifting hard 1-2 and 2-3. Research shows it is a known problem of manufacturer addresses under gm tech serv bulletin 01-07-30-023b. Further, internet search indicates that problem is manufacturers design error, and that only permanent fix is to use an aftermarket suppliers re-designed replacement part. Currently, I am in the position of having to seek repair at estimated costs ranging from $1800-2800 from local service providers.

The transmission on my 1998 GMC surburban failed. I was told by the dealer and another transmission specialist that this particular problem has been common to the 1997-98 GMC and Chevrolet surburbans, tahoes and comparable vehicles. It is not fair to consumers for an auto maker to know about severe problems like this with vehicles and not issue a recall or correct the problem. Of the 86 complaints listed on your website for this model, 7 involved and others involved the drivetrain which can be an associated problem.

Automatic transmission shifts hard from 1st to 2nd gear.

1998 GMC Suburban transmission problems. Our vehicle was special ordered from gmac in 1997. The issues in our transmission started late last summer, 2002. There is a very noticeable "bump" when starting from a standstill and going from 1st to 2nd and 2nd to 3rd gears. As stated in other complaints this is our family vehicle transporting or 3 small children.

Vehicle was put into neutral from park without vehicle running and without brakes pushed on causing vehicle to roll backwards with drivers side door open into a pole causing door to be damaged.

Have owned '90gmc c1500 p/u & '99 GMC c1500 Suburban in past 12 years; both vehicles have had same problems w/ front brake pull/wear; suspension; brake pipes; engine/trans. Hesitation, hang. . . . ; corroded + battery cables, batteries; leaking hvac ducts; and on & on. How in the world does 12+/- years of documented brake problems across vehicle lines/models not warrant a massive recall and/or compensation to owners for obviously faulty engineering, materials, etc. . . . . ????!!!! I suppose the Ford/firestone problems took precedence? can you say "class action"??.

We have replaced our automatic transmission twice since owning our 96 GMC Suburban. We have owned the truck since 1998.

Began shifting hard from 1-2 and 3-4. Does so after driving. Can stop and turn off engine and it will stop for a while. I have read many similar complaints. 3 and 4 transmissions have been replaced and same thing occurs after 10-20,000 miles. Local dealer says it is a common problem, but GMC will not cover.

Transmission "races" between 2nd and 3rd, then clunks hard to shift.

Harsh 1st to 2nd upshift; based on my research, gm has been aware of problem but has been unresponsive.

The front brakes of the Suburban has been replaced for the second time with raybestos (lifetime wear) brake shoes. My transmission started shifting very hard, as if someone had rearended the truck at a slow speed. I took it to aamco transmission's for repears. Aamco rebuilt the transmission, but did'nt fix the problem. After $2200. 00 and the fifth attemt to fix the problem I took it to a GMC dealer and they actually fixed the problem the first time for $308.

Vehicle is experiencing transmission problems continually requires repairing.

Transmission overheated (unknown reason per dealer) vented all fluid. Transmission had to be replaced.

No summary.

Vehicle was moving on the interstate while at 65 mph on cruise control. The automatic gear shift column was struck by the passenger and the transmission was sent into reverse. This action caused the brakes to lockup and the control mechanical lock on the wheel column was locked into a right hand turn with no way to control the vehicle. The vehilce started to skid out of control and then proceeded to roll over three times. All occupants were in saftey belts except my daughter who was int the back seat asleep. The vehicle was totally destroyed. It took resecue crews to remove myself the driver and daughter who was trapped in the back. We were transported via ambulance to a local hospital. All five passengers were released with only minor bruises and cuts. I would like to find out why the steering column lock and why a safety feature is not provided to keep the transmission from being accidently put into reverse while the vehicle is traveling in drive. Please help me find a solution to this potential problem.

While driving at 55 mph vehicle is shifting very hard from first to second gear. Transmission has been replaced twice. Dealer can't determine the problem.

Vehicle surged forward when consumer went to put vehicle into reverse causing collision with another vehicle. Nlm.

Problems with 1999 GMC Suburban transmission equipment. Dealer notified.

Vehicle has defective transmission/ engine, transaxle,ring and pinion,gear/engine bearing/brake booster/ front brake pads and calipers,and suspension. Consumer feels vehicle was poorly manufactured, especially when pulling trailor or with load. Please provide further information.

Example of problem, when the truck has run 50 miles or so on the freeway, stop at off ramp. The truck shifts hard from 1st to 2 nd when I pull away. This continues until I shut the truck off, wait a few minutes and start again. Then it is fine for a while and will repeat the same, sometimes weeks apart, more often in the summer months. My driving pattern is one of short trips, so I guess this is why my problem is sparodic. I have read many complaints one web sites about this problem with other gm cars and trucks,the code #1870 seems to figure in most cases, most people have had no luck with gm, and are stuck with bills of 2-3000 dollars. I hope you can check this out, seems to cover gm cars and trucks from the 80s-01. Thank's graham brown. Dt.

This happens only when the vehicle is completely warmed up. No safety defect.

No summary listed for above vehicle.

When driving at 50 mph the adaptor within the transmission fell down, causing overheating and smoke to fill the passenger compartment. Also, passenger's compartment became very hot. Consumer has contacted dealer, dealer has replaced the transmission.
