Shift cable broke between the shifter and the transmission while shifting from drive to reverse to park on a street. If this had happen while shifting down gear to lower speed while driving down a hill, a loss of control of the vehicle would have happen that would have LED to a crash with extreme property damage and most likely driver and passenger injury and possible death. The vehicle was towed to ourisman chevrolet in marlow heights maryland for repair after the tow truck driver manually shifted the transmission into drive from underneath the vehicle that would've been extremely dangerous for the tow driver to do if the vehicle had been facing down hill or in a heavy traffic situation. For some reason, however, my vehicle still hasn't been repaired nor have I've been given a reason as to why.

Dear sir/madam, I have a 2003 gmc envoy slt model 4.2l v6 4wd and as I was backing into my garage I heard a loud bang and whinning noise and I now have no reverse gear and when I select the drive gear on the automatic transmission I have a whinning noise, I have read the blogs on this issue and I believe that gm and gmc are very aware of this problem, this repair will cost me up to $2,800.00 plus tax to have the transmission removed and a re-manufactured on replaced on my vehicle. I was just glad that this matter happened at my residence and not on some back road in west va., I believe that as stated, gm and gmc is very aware of the problem with the 4l603 transmission that were used in these vehicles' and the problem with the sun-shell and the reaction sun gears that are like a grenade exploding inside the transmission. I would like for a recall to be started on this problem and the owners to be paid back on all of these repairs. The consumer stated the air ride suspension that was installed on the vehicle is dangerous. The air ride suspension deflated on both sides on the rear of the vehicle, which caused the vehicle to bottom out on stops. Updated 07/08/15

The gear shift selector cable became disengaged from the transmission while backing out of a parking spot. According to my mechanic, there is a small plastic bushing that became brittle and fell off causing the failure of the cable to maintain a connection with the transmission. This caused my transmission to become locked in the park position and unable to be moved into any other drive. While I was in a safe location, I'm concerned that other drivers in similar situations will become stranded in locations that are not safe. I conducted a recall search and found that this item has not been recalled. I placed a call to general motors and lodged a complaint. According to gm, they have received a number of complaints about this issue but are not issuing a recall at this time. I asked gm to provide me the number of complaints they have received about this and they declined to give me that information. I am seeking to file this complaint, have it reviewed, and determine whether a recall should be issued for this vehicle.

The transmission failed in my 2003 gmc envoy with approx 95,000 miles. While driving down the road I went to pass a slow moving vehicle. As the transmission down shifted there was a "bang" so I pulled over to look under the truck, and made sure nothing had fallen off. I got back in the s.u.v. And made my way back home with no problem. The next day when I went to back out of my drive way there was no reverse. I called a local gm dealership and was told that the problem appears to the sunshell gear. According to multiple post online, seems to be a common failure among envoy's and trailblazer. I checked the fluid and it appears to be fine, not low, not burnt, and still red and clean.

It appears that the transmission/solenoid failed. The SUV does not always go into gear. Slips out of gear. After SUV sits for a while it goes into gear only to resort back to afore mentioned problem.

First problem occurred in 2008, driving to work in 2003 gmc envoy slt (original owner) heard clunking noise when downshifting. Took car in to shop for repair (just over 50k miles so out of warranty). Shop explained that the transmission needed to be replaced $4000 with one year warranty. Since I was planning on driving cross country decided to do the repair. One year later, driving and trying to accelerate on a ramp to find SUV stuck in second gear and wouldn't accelerate while RPM kept going up. Also heard clunking when downshifting. Pulled over and tried to get gears to shift by slowing down and speeding up (to get RPM to drop). Drove car to dealer who stated I needed a new transmission (again). Dealer removed transmission and "found input bushing in pump bad. And reverse drum. And had heavy metal contamination". When asked why this is my third transmission in six years the service agent said "bad luck". Both replacement transmissions were rebuilds. The current transmission is not under warranty.
