The vehicle failed to shift into park. The vehicle was taken to the dealer where the technician diagnosed that there was a broken wire in the BTSI solenoid terminal which needed to be replaced. The vehicle was repaired by re wiring the ground wire to the shifter where the pin had broken. On May 3rd the key got stuck in the ignition and would not come out. Let the car sit for 24 hours the battery died and the key released out of the ignition. Took the car to the dealership on May 5, 2014 and the shifter wires were re constructed. Car still acts as if the shifter is not going to shift.

Started having trouble with my transmission a while back. If I was at a stop and tried to accelerate it was slowly take of then all of sudden slam into the right gear then take off. It also happened even if I didnt come to a complete stop and tried to go again. My check engine light came on after about a month of this happening. I had it checked. It was a shift solenoid. Since I was still under warranty I had it replaced. It was fine till about a two weeks ago 08/20/2013. Now my transmission is doing the same thing again.

After stopping, I push on the accelerator, the engine revs but the transmission does not engage, after two seconds the car will slam into gear and violently lurch forward. Powerful enough to strain my neck. Very dangerous.

2007 Impala ss. Transmission hesitation occurs when going around 45-60 mph. Car semi-engages shifting, but then backs out, giving a chugging sensation while driving in that speed range. Higher speeds above 60 produces an incredible screech/whine noise. Currently in shop for transmission diagnostics. At 74,000 miles clutch was replaced due to it being cracked in half. GM has either mad poor transmission engineering, using shotty parts, or this transmission is overly underrated for the power of the engine.

First, when I slow down to turn a corner, I take my foot off the gas. After the turn, when I press the gas I have no power. It doesn't die, it just won't go anywhere for about 15-20 seconds, no power. That doesn't sound like a long time unless you are sitting in the middle of a busy intersection. I have to come to a complete stop for about 20-30 seconds, then take off. Sometimes it goes, but feels like it jerks into gear. That's ok at stop signs but stop lights that turn green as I approach can be dangerous. Also, if I turn a corner onto another street, it hesitates. And sometimes I have almost been hit from behind. People expect you to turn and proceed. When you just stop, they may not. I also noticed one day, when I just coast on a level road, my car sometimes accelerates for quite a while, instead of slowing down immediately. I once took my foot off the gas at 45 mph and coasted on flat road for 2.5 miles. The latest related problem is.. spring 2013, twice, I turned a corner and it just died. I had to pull over to the side of the road to get out of traffic. After a few minutes, it cranked back up. Thankfully, I was on a city street and not a four lane road. I also have problems with parking. I put my foot on the brakes and pull into parking spot. When I put it in park, it lunges forward. Or if I stop in traffic, sometimes it lunges after it stops. I have to make sure that I leave plenty of room in front for this problem. I think it has something to do with the computer allowing the gas to flow or stop. I had the transmission rebuilt and it still does it.

When I put my car in park I cannot get the key to disengage from the ignition so that I am able to take the key out. I have tried jiggling the gear shift etc and it will not come out regardless of what I try.

Occasionally, when starting from a stopped position the engine will rev up and then the transmission will kick in to gear. Occasionally it slips on hills also. We generally do not have to merge into high speed traffic but if the transmission slipped at that time there could be serious consequences. The dealer has been unable to fix the problem after five visits, and apparently will not do anything until they themselves experience the transmission slip.

At a stop light. Feels like transmission is not in gear, engine revs 2500/3000rpm, then trans goes in gear. Told by dealer if using left foot on brake at a stop, this would cause the problem. They offered no help. Was told without codes there is no problem with transmission! when I got car it was leaking trans fluid.took it back to dealer, to have leak fixed. At another shop I use, while car was on lift you could see trans pan on valve body had been off. Trans has for sure been worked on! as you might guess it will not do this at the dealer.I let the car with them for 1 week, for them to drive.when I got car back they put all of 3miles on it.

Reported that car would jerk (kick into gear late) when accelerating from stop to start. At 74,000 we made our first claim with local dealer. They couldn't duplicate the concern. Brought car in two more time because it got worse. Felt like someone was hitting me from the back. My car often kicks out of gear on a left turn. On two separate occasions, I was almost T-boned. They never found the issue until 121,000. That was when they declared that the transmission needed to be replaced. GM doesn't want to cover the repair now that the vehicle is out ofwarranty. I have researched and found way too many transmission issues with these model vehicles. GM really should investigate this concern. I advise anyone to pester GM about this concern. Afterall, we are the consumers. Unfortunately it's too late for me, I don't trust their products anymore.

As I was driving the engine light came on and the display read reduced engine power. The car slowed down and resisted as I accelerated. I can only drive about 20 miles per hour. There is no warning and there is a decrease in acceleration. There was no warning and I have my child in the car. This is very dangerous.

Slip in torque conversion around 30 to 45. Also, you'll be taking off from a stop and when you start to press the gas it delays, then slams into motion almost like being hit from behind. * did not know about this site. Had it to the dealer 3X, they said they found nothing wrong. It is sporatic and does not happen daily.

Returning home from work on interstate noticed it took higher rpms to get up to the 65mph speed limit. After driving for a few minutes I stopped at a red light. The vehicle could then only get up to 40mph and lost power down to 10mph when I pulled over and called it a day. Currently at the shop with 10 different codes showing. Unfortunately I have had it jsut over 5 years and not in warranty any more.

  • 51,000 miles
Exiting the dartmouth street parking garage (underground) on dartmouth St. Boston, MA. Exit ramp is a moderate incline. As I approached the garage attendant booth to pay parking fee, I let off the accelerator letting the car coast to a stop while I retrieved the parking time/date receipt. When I located the receipt (about 5 seconds) from the center console I looked up to find the car was rolling backwards down the ramp toward a concrete wall (by this time) approximately 15 mph. Note: I am a 50 year old, (male) retired police office and was trained in radar speed enforcement including certified in speed estimation and I am also "evoc" (emergency vehicle operator course) trained. I was able to stop the car before hitting the wall, another vehicle, or any pedestrians. I feel a tragedy could have occurred had someone been walking in the garage. The car seems to have no ability to "hill hold" when in "drive" at idle. I was shocked at how fast the auto accelerated backward. I have personally driven approximately 750,000+ miles without an at fault collision. The car seems to do this whenever on an incline and on a few other occasions had occurred in parking lots rolling (forward as well as backward) as soon as shifted out of "park" in the fraction of a second time that it takes to move my driving foot (right) from brake (due to park interlock) to accelerator. Note: This auto is a 2007 Chevrolet Impala ss with 5.3L V8 engine and four speed automatic transmission. My primary concern is that Impala are generally driven by elderly drivers with slower reflexes than myself. I have further found numerous online forum discussions of this issue by owners of all engine equipped Chevrolet Impala.

The contact owns a 2007 Chevrolet Impala. The contact stated that the engine rpms suddenly increased as the vehicle failed to respond to acceleration attempts. In addition, the transmission hesitated to engage in gear but once it did, it would shift hard. The vehicle was taken to the dealer who diagnosed that the tcc valve was leaking, causing transmission fluid to leak out of the torque converter. As a result, the transmission had to be rebuilt. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 37,000 and the current mileage was 39,000.
