Bucking when shifting gears. Engine cutting off. Had to replace solenoids and torque converter. Problems started at 115,000 miles.

June 8 2013: when driving, noticed on the freeway, it wasn't smooth at times. The transmission's shifting was pretty rough. No indication of any issues popped up on dashboard. When arriving at freeway ramp, it felt like I was hydroplaning, but on gravel. Then, noticed when pressing the accelerator, was not going anywhere, but felt like I was in neutral. Was able to pull in and take a look. . . Transmission fluid was fine. . . Nothing popped up on the dashboard. Nothing! the indicators for tires, oil, etc were showing info, but nothing to indicate it had died!! dropped it off at the dealership - had just bought it in July 2012. 11 months later, this?!?!? they are saying they have never seen it this bad, even when compared to other ollllllder cars, this was the worst. They have to replace the entire transmission. They called in the gm people to take a look at it. Their auto trans concern: customer states towed in transmission will not move at time of write up reverse and forward working input and reaction carrier excessive clearance metal in torque converter. , valve body, burnt clutches call tac case #71-1194752825 prive comp advised to replace trans due to cost with srta. Ord serial #619asbwjr6j prelacw tih srta flush code 693ffee5 they replaced it under warranty. . . Total cost was $4400 Aug. 29, 2017. The replaced transmission failed. We were on the freeway, just got off, while in motion, there was some really rough vibration. Could not go any faster than 25 mph. No light indications on the dashboard. It tells me if flat tire, blinker is on, the temperature outside, etc etc, but nothing wrong with the transmission. I'm not sure if it's related, but we smelled vinegar every time we started the car for about 4 days straight. We noticed that when accelerating, it's okay, but when letting off the gas on the freeway, it "shudders. ".

Transmission replaced due to torque converter failure. 77000 miles on my 2011 Impala. This vehicle is not driven hard. Driving at about 40 mph- the vehicle slipped out of gear. Very scary for this to happen. Traffic was very light. I was fearful because the street I was on was only one lane in each direction, and not much of a shoulder. I felt very lucky I was not on the freeway. This I believe could have been very dangerous. I was able to drive the car at a very slow speed to a dealership that was less than a mile away. Sad part I was over 300 miles from home. Torque converter failure caused heavy metal debris in the transmission leaving me with a bill totaling $3368. 52. (plus other expenses due to my distance from home. ).

Failed torque converter. The torque converter would slip when shifting from reverse to forward (drive). It would slam into drive, grin the gears and cause the tires to squeak (spin). On April 28, hedrick's Chevrolet 961 w shaw, clovis, CA, replaced the original torque converter, with a remanufactured convertor, part number 17804457 (1), plus the following parts:17804457(1)-core return, 24264377 (1)- seal kit, 25886620(2)- gasket,10333578(1) - gasket, 12609163(1) - gasket. It is a warranty clovered part.

Tl- the contact owns a 2007 Chevrolet Impala. The contact stated that the engine had a sudden increase on engine rpms causing the vehicle to revved up and it failed to move. The contact mentioned that the transmission would hesitate to go into gear but once it did it shifted hard. The vehicle was taken to the dealer who diagnosed that the tcc valve was leaking causing the transmission fluid to leak out of the torque converter. As a result, the transmission has to be rebuild. 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. Pm.

Transmission slipping, hard shifts, broken motor mounts. Transmission acts like it's not in gear, doesn't engage until about 2,000 rpm then slams into gear. Also slips when shifting from 1st to 2nd and again when in 4th gear. Transmission failure, the transmission fails to fully engage in to any gear when it is supposed to, it will slip and catch from a stop, the torque converter fails to lock up and all gears slip under moderate to heavy acceleration.

The car is shifting hard from 1st to 2nd gear and every once in a while when I slow down around a curve and then the car has to shift down and back up right away. This has been getting worse and worse and from what I have been reading, it probably isn't the transmission but with the vacuum modular or torque converter. I also had a 2005 and recently traded it in for a different vehicle, but it had the same thing with shifting hard between 1st and 2nd.

2008 Chevrolet Impala ss with 5. 3l ls4 engine and 4t65e-hd transmission experience torque converter failure at 55k miles requiring full transmission replacement. Replacement transmission beginning to exhibit same torque converter shudder behavior again and warranty will be expiring soon. 4t65e-hd transmission only rated for 280 ft-lbs torque, ls4 v8 produces 323 ft-lbs. This is clearly negligence on the part of general motors and a solution must be reached for owners of these vehicles!.

Impala "ss" with only approximately 71,000 miles, major transmission malfunction / failure without any prior warning. Vehicle had only been serviced at gm dealership since purchased, all regular maintenance followed. Transmission slippage combined with harsh shifting, torque converter shudder, grinding noises from gears. Vehicle would alternate between not going forward or, once moving, very difficult to stop vehicle because transmission did not disengage (nearly rear ended other vehicles, had to stand on brake pedal). No warning lights nor dash indicators, but remote diagnostic via onstar confirmed transmission failure and directed for immediate repair. Valve body, pressure regular, all solenoids (rebuild) replaced under gmpp extended warranty coverage. Not even two weeks later, problems returned but worse. Nhtsa campaign # 10021844 and TSB # 070730012c seem to address this issue. Vehicle now at gm dealership being assessed. Onstar diagnostics found no issue. Still no warning indicators, but vehicle have high rpm without any forward motion when accelerator depressed. Rpms would also bounce up and down erratically on highway at steady speed, vibrations and whining noises from transmission. Apparently this is known defect with multiple vehicles equipped with the 4t65-e transmission, but there has never been any recall. Cost of repairs for this between $4,000 and $6,000 if not under warranty. This likely effects hundreds of thousands of gm vehicles covering many model years.

Transmission has been rebuilt once, then subsequently replaced with a remanufactured unit from general motors. This remanufactured transmission is now displaying anomalous behavior. Prior to each failure, the transmission exhibited a variety of incorrect behavior, including rapid torque converter clutch locking and unlocking, slipping and reving from a stop, without the car moving, then suddenly slamming into gear with the car moving away from rest. The most recent issue has been an oscillation on 4-3 downshifts at approximately 60 mph, as well as excessive transmission heat build-up with the torque converter unlocked. The first time the transmission displayed odd behavior, which was torque converter lock and unlock at cruising speeds, dealer drove the car acknowledged the problem, and upon disassembly, found torque converter clutch material in the pan. They rebuilt the transmission with new soft parts and replaced the converter. Vehicle had 59,000 and this was all performed under warranty. About 23,000 miles later, when pulling away from a stop, the engine would rev up momentarily, but the car would not move. It would then slam into gear and move off. Dealer confirmed issue, disassembled, and determined that the torque converter clutch had again failed. Dealer replaced transmission with a remanufactured unit. This was all done under warranty. Vehicle had approximately 86000 miles at this time. Immediately upon receiving car back after replacement of transmission, noted oscillation on 4-3 downshifts, as well as much higher transmission temperatures with converter unlocked (about 40 degrees higher), as well as excessive looseness of the torque converter. Returned to dealer, who claimed all was normal. Since that time, warranty has expired. The oscillation and heat issues have worsened, and the car is now being serviced at an independent shop and having a partial rebuild.

The contact owns a 2004 Chevrolet Impala. While driving approximately 60 mph, the gear shifter failed to shift into all gears. The vehicle was taken to the dealer where it was diagnosed that the torque converter and clutch assembly failed and needed to be replaced. The vehicle was repaired. In addition, while the vehicle was in reverse, there was a delay when shifting into gear. Also, the vehicle would jerk when shifted into drive and the passing gear would get rough going in and out of gear. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failures. The approximate failure mileage was 134,273.

Transmission lunges from a dead stop upon acceleration. Does not move with increased rpms until torque converter bangs. Problem has existed since purchase in 2006 with 11,000 miles. Taken to dealer multiple times with no problem found. Multiple complaints with this per internet search. Chevrolet evidently will not own up to this problem.

There are 2 people other than myself that have Chevrolet Impalas. One person has a 2005 but the other and myself have the 2004. All three are having the same problem you will be stopped and start the gas pedal and there is a jerk . Feels like some one has hit the back of the car. (transmission or torque converter. ).

Transmission failure. Vehicle making gear whining, and transmission slips at highway speed. Service shop indicated that there is a "solenoid switch" that is stuck in the torque converter. There is a 50/50 chance that the drum in the torque converter is cracked, therefore shop won't invest the large amount of labor required to replace this stuck switch. The repair will require a complete transmission rebuild. 120,000 miles on vehicle. $1500 of repairs for a stuck, $20 switch. Not right.

I noticed that my transmission shifts very hard when it warms up. I took to Chevrolet dealer, they changed my transmission mounts, and dog bones. I paid quite a few dollars and my vehicle still has this same problem. The vehicle has 85,000 miles, but I,ve maintained the vehicle very well. I,ve also had problems with my steering play. The dealer changed some parts in the assembly which is better. I'm a mechanic and I don't beleive that there was anything wrong with my drivetrain mounts, but it's in the transmission. I paid alot of money and still have the same problem. Since owning the car I had problems with the drivers window. The motor was changed once under warranty now it's doing the same thing again. The problem is it will go down but won't go up sometimes.

I have had numerous problems from day one with this car. At 60,000 miles, I had a transmission failure. There was a whining noise that came from the engine compartment, usually at highway speeds in 4th gear, or overdrive. I had the car diagnosed at a transmissioin shop, and was told that it was going to need to be completely rebuilt. This failure could have occurred on the highway, if I had not been vigilant in my investigation of the problem. As a result, I had a huge repair bill, was without the car for 1 week, and had to pay for a rental to drive to work. To correct the problem the transmission and torque converter had to be rebuilt, and repalced. Specific parts that I know of were, the "torrington bearing", which caused failure of a set of planetary gears, and the 4th gear spline. The repairman said that the bearing and the 4th gear spline are of substandard quality, and that replacement parts have purposely been made stronger, and heat treated, because this is a known problem in these transmissoins. 60'000 miles is much too early for a failure of this type to occur. Total repair bill was over $2,500. 00.

Consumer stated the torque converter clutch takes a long time to lock up on the transmission in cold weather, consumer was informed by a gm rep that this occurrence is normal, after checking in the gm service manual, consumer discovered the torque converter clutch does not lock up until the fluid temperature in the transmission reaches 266 degrees fahrenheit, consumer stated when the torque converter clutch is not locked up, the vehicles highway gas mileage is not close to what was advertised on the price sticker of car.
