Automatic Transmission Problems of Chevrolet Impala - part 2

2005 chevy Impala, not only mine but I've also read others that on an incline they tend to roll backwards when foot is taken of brake, I believe this is a safety problem--not something that is taken for granted with this vehicle. Thanks.

2006-2009 Chevrolet Impala ss, 2006-2007 Chevrolet monte carlo ss, 2005-2008 pontiac grand prix gxp and 2007-2008 Buick lacross super with the ls4 5. 3l v8 engine and the 4t65e-hd transmission mn7. The ls4 v8 engine is rated by gm at 323 lb-ft of torque. Allegedly, the documents from gm for the transaxle mated to this motor is only rated for 280 lb-ft of engine torque; 43 lb-ft of torque lower than the output of the engine. This could possibly leave a vehicle equipped with this motor and transaxle combination with a high failure rate and a possible safety hazard while in traffic. . Read more...

On the 2005 chevy Impala, it is possible to shift the car into any gear without depressing the brake when the ignition is in the "acc" position and without the car being started.

Power train failure: first sign of problem was harsh shifting, had the transmission fluid and filter changed, still had same problem. Before I found the service bulletins on this problem the planetary gears got chewed up by a broken piece of metal, had to rebuild the transmission $1800. Filed complaint with gm, since I did not have it repaired at a dealer (for twice the price) they would not help. Now I have a 2001 monte carlo showing the same harsh shifting. The transmission has be flushed by the dealer and they put an additive into the transmission fluid to help the sticky value problem, did not work. There is a pattern here and gm will not stand behind their product.

When in drive car rolls backwards even on slight incline, also rolls forwards in reverse even on slight hill or incline, have taken it to a dealer and they said this is normal of these cars.

This is rental car from alamo. Car was parked and engine was stopped on a little inclined roadside. All people exited car. Car was suddenly moved backwards and I had to jump in to the car and applied emergency brake. Car was stopped in the middle of the road. Right side door hit road sign and car damaged. It can be very very risky if there was other cars or people on the road.

I have a 2002 Chevrolet Impala. It has around 53,000 miles on it. My wife drives the car and it has been driven slowly. About 3 weeks ago she told me the car shifted hard and I drove it and found that problem also. That went away for 2 weeks and it happened again. We were referred to a independent transmission shop and we were told that the transmission in the Impala has been having problems and we were told it needed to be rebuilt. I then took the car to the chevy dealer and they said they is some problems but just wouldnt get specific with me. I then went to another independent transmission shop and was told the same thing as the first shop told me and that was I needed this rebuilt. They said the transmission is a bad design and want $2400. To $2600. To fix it. This is the same price as the first place gave me. I think if this is so common of a problem g. M. Should do something about it. I am going back to the chevy dealer and am going to ask them just what they can do for me. I'm not a happy person, this car has not been driven hard and infact it's been treated nicely. I can't find a recall on it but it seems like there should be one in effect for it. I also think this problem could be a serious road hassard if the transmission goes out while being driven.

On 4/20/05 while driving,grinding noise was heard. Vehicle began to slow down unintentionally ,and upon pushing the gas pedal, car would not speed up. This occurred on dry pavement on highway. Car was regularly serviced with records available. This problem occurred about every 6 months.

2001 Chevrolet Impala was involved in a minor accident and afterwards the transmission would no longer function. The transmission had no reverse and had shifting problems. The technician determined that the thrust bearings broke and damaged the sun gear, input carrier and reaction sun gear. The technician indicated the this is a common problem with this transmission and that it's failure was not related to the accident. The manufacturer issued service bulletins referencing transmission problems.

Just purchased a 2002 Impala with an automatic transmissiion with less than 20,000 miles. The car rolls backwards at an incline when in drive. Contacted dealer and was told this is a known problem and that all automatic do this today. Dealer refused to do anything. I consider this a hazard. Have been driving automatic transmissions for years and never experienced this before.

Upon acceleration car pulls to the right. Upon deceleration or traveling in reverse, car pulls to the left.

Car parked on hill with emergency brake engaged. When brake was released, car rolled backwardsas if in neutralal, even though it was in park.

Transmission blew from the inside out.

My husband said that his car was driving poorly for about a month or so before it broke down on a busy road. Since this is the third Chevrolet transmission to break down on both my husband and I we knew that was the problem. As a result we were without a car for about a week. Luckily there was no accident but there very well could have been. The car just died at a red light. Chevrolet replaced this transmission with a rebuilt transmission,because it was still under the original factory warranty. The warranty on the rebuilt part was for only 90 days. Last year when we had to pay for the transmission to be replaced on my 1997 venture after only 52,000 miles the warranty given was for one year.

Since the vehicle was bought in 2004 it has been towed 3 times to the dealer because the vehicle would not go into reverse. Since a new transmission was put in the vehicle still has this problem. This has happened over a dozen of times. Updated 09/25/07.

My 2000 chevy Impala has transmission problems that may result in me having to purchase another one. This car was shipped out with a 4t65-e tranny, which has more problems than the law should approve. In my current research I have found hundreds of recalls concerning the 4t65-e all in different gm vehicles. My Impala's tranny is about to go, the symptoms are hard shifting from 1st to 2nd gear. I don't think it's fair that I was sold a car with a defective transmission. This problem should be corrected.

While accelerating from a stop sign, car shook all over and I heard a loud bang. The car would not move at all. I coasted to the edge of the road where I waited for a tow truck. The dealerships service manager informed me after about a week, that my planetary gear had exploded. He also stated that the fluid filter was full of metal shavings. He stated to us that there was nothing that I could have done to prevent this from happening. My new transmission cost me $2200. This car has just 55000 miles on it. It is absolutely insane that I am paying all of this money to repair this car, that is practically new. I have contacted gm's corporate customer service people and they will offer no assistance in this matter. The service I received from them was poor. The case was actually lost once therefore I had to start all over again. The woman who then took over the case bold face lied to my fiance and then back pedaled by saying that there was another case just like mine and the woman just happened to have the same name as me. What a coincidence. In addition to this, just 10 days prior to the transmission's death, I had to replace a catalytic converter in the vehicle.

I have a Chevrolet Impala 2001. Just last week the transmission completely went. I just received word from the transmission shop I took it to. The estimate is $1700. 00. Which is ridiculous for a car with 38,500 miles. Gm stated that since it is over warranty there is nothing they could do. Second they stated that the Impala would need to be at a gm dealer for them to even open a complaint with the issue. Why would I take it to a gm dealer to have them tell me sorry out of warranty and then charge me double the quote of a transmission shop. Fool me once shame on you. But fool me twice shame on me. Any advise you could offer would be appreciated.

My 2001 Impala began having loss of power/slipping during acceleration at low speeds around 30,000 miles, dealer looked at car and could not duplicat 2 times. Car scontiued to have the problem and dealer felt that the valve body should be replaced and toe set. At 37,400 miles I was driving along and suddenly loss operation of vehicle whil going through intersection, coasted into gas station tried all gears of car and was unable to move car forward or reverse. Had car towed to dealership. Transmission repair of planetaries and bands was performed that was August 25, 2003. On September 10 check engine light came on and I had it diagnosed at independent mechanic shop and was told that 2 transmission codes were coming up they were 742 and 748. Gm extended warranty would not allow repair to be done by any one else but Chevrolet dealership, I took the vehicle into dealership on October 6 and was told on the 9th that they could not duplicate the problem. I will be picking up my car tomorrow and waiting for the next time that the check engine light comes on to take it back to the dealer.

Car won't move at times. Removed transmission, inspected internal parts all okay except valve body replaced, sticking valve body and gaskets.

Transmission died today. Coasted into a parking spot. 6-30-03 car was in for third 'low coolant' light. A costly correction was made by the dealer. Previously in 4-03 and 8-02, installed new sensor both times.

Consumer stated that when putting vehicle in park on a hill the vehicle would pop out of park and start to roll back in reverse, causing damage to the vehicle. Dealer notified.

Steering colum in my car has a clunk/vibratoin. The engine cradle was replaced and I was told that this was the problem , but later the noise returned after the 36000 warranty was over. Now dealer tells me that my extended warranty that I paid for would not cover the repair. Also the car is having tranmission problems, still waiting to see if they can find the problem. . . . Have been told that if no check engine light comes on then there is nothing wrong. I am going to leave with the dealer and have the service mgr drive, but not a lot of hope in this.

While driving at any speed transmission jerked. Dealer inspected and stated the was the code-po742. Consumer stated this vehicle was no longer on warranty.

Consumer states that while driving at any speed and with no warning transmission will lock up, locking the rear tires, and it will be hard to control the vehicle. Consumer will be forced to pull over.

When the vehicle accelerated from a stop on a small or large incline the vehicle rolled backwards excessively and almost caused a collision. Returned usps, 2nd attempt made 05/21/03 failed.

The vehicle rolled backwards while on a hill.

When on any grade of incline the car will begin to roll backwards unless gas pedal is pressed quickly and quite hard. This almost resulted in me hitting a car behind me while waiting for a red light on an incline when I removed my foot from the brake pedal. This has happened several times now and I have to keep my foot on the brake as I begin to accelerate or the roll back occurs. Also attempting to park at my daughters school where the parking spots have to be pulled up into, the car rolls back rather quickly as if it were in neutral. I have also noticed that it has some problems advancing it's gears if the engine is under strain. I'm very worried that my car rolling back will result in accident.

Transmission went out, have to be completely rebuilt. Metal pieces were found in fluid. Vehicle previously in for service due to the pressure modulator in transmission went out. Felt like you were driving and shifting without a clutch if the car was a stick shift. Prior to that, the computer module went out, causing the battery to drain over night and having to jump start it. Before that, the automatic traction control system went out. Found out it was a faulty sensor in the back brake area. Before that, the front rotors were severely wrapped and had to be replaced.

At 39,000 miles the transmission malfunctioned while shifting into gear, which caused a lurching movement every time. Initially, the transmission problem started at 26k miles. The dealer stated stated that the steering wheel rod needed replacing and lubrication. The difficulty returned. The dealer stated that nothing was wrong. The vehicle had begun to lurch into gear when stopped, skipped gears in reverse, and sometimes would not drop into proper gear.

No crashes.

2002 Chevrolet Impala, in the winter below 20 degrees car must warm up before it can be shifted in to drive. It has been this way since new.

Car running rough, wanted to stall, dealer found no problem.

Consumer states vehicle has excessive rollback on inclines when accelerating from a stopped position. Nlm.
