In fact, we cover a class action lawsuit brought against GM back in April, complaints from ownersand even a recommendation that GM replace the eight-speed altogether with a new unit as quickly as possible.
As of July 8 th, GM began using a new type of Mobil 1 automatic transmission fluid for the troublesome transmissions. Customers that complain of shuddering and harsh shifting characteristics in the 8-speed GM transmissions are recommended for a trans fluid flush. As of August 7 thGM dealers should also be flushing all potentially affected new vehicles on the lot.
The GM 8L45 eight-speed automatic transmission. The issues with the 8-speed GM transmission are two-fold. First, some customers report the transmission shuddering frequently. Secondly, the shifts are very harsh between first to second, and then second down to first, especially when accelerating and the transmission is upshifting or decelerating and the transmission is downshifting.
These conditions are most commonly observed under light and medium throttle applications, and as often during full throttle applications. However, a new fluid flush appears to fix the issues, with some customers beginning to report a dramatic change in shift quality after swapping out the old juice.
Driving the vehicle for about a week or so improves shift quality even further as the new fluid cleans things up inside the transmission and the adaptive shift algorithms relearn various parameters. Hopefully the new fluid swap will provide a lasting fix.

TSB Seems To Fix 8-Speed Automatic GM Transmission Problems
Any comments pro or con. The main issue is the Shudder that happens driving at 40 MPH on a slight upgrade. This is what most report on the forums. This is only an issue on some and not all of these transmissions.
GM has changed the programming, the Converters and even the transmissions with no correction for some. Now they have changed the fluid several times. The latest with a flush appears to be working.
The fluid they were using was absorbing moisture and creating the issue. The hard shift in first gear is when it is cold. More load the smoother it is. Once warm it is gone. The delay is another issue that some of them had a seal that let the converter leak down. It needed to fill before you would move. If you stepped on the gas before it filled then it would hit hard. There is another TSB on this and they just replace the transmission.June 19, — A GM truck transmission lawsuit may continue for GMC Canyon and Chevrolet Colorado owners in Florida, but a federal judge says there will be no nationwide class action concerning the 6L50 transmissions.
The lawsuit alleges — GMC Canyon and Chevrolet Colorado trucks are equipped with transmissions that experience " premature internal wear, sudden acceleration, delay in downshifts, delayed acceleration and difficulty stopping the vehicle, and eventually suffers a catastrophic failure. According to the plaintiff who filed the proposed class action, the transmissions harshly engage, jerk, slip, buck and kick.
According to the plaintiff, the General Motors truck transmissions have caused owners to complain to the automaker, federal safety regulators and to CarComplaints. The plaintiff says his new Chevy Colorado had trouble downshifting when going up hills, so the dealer reprogrammed the transmission and engine control modules.
But the plaintiff says the repairs didn't end the alleged transmission problems and a few years later the truck started shuddering when accelerating. According to the lawsuit, the dealership returned the truck to the plaintiff even though no repairs were made. General Motors filed a motion to dismiss the truck lawsuit and succeeded in convincing the judge a nationwide class action could not proceed.
According to the judge, the plaintiff who filed the lawsuit didn't base his claims on the application of other states' laws. Therefore, the plaintiff lacks standing to bring claims on behalf of a nationwide class of GMC Canyon and Chevrolet Colorado owners.
According to the plaintiff, General Motors breached implied warranties, but the judge says, " [U]nder Florida law, a plaintiff cannot recover economic losses for breach of implied warranty in the absence of privity. However, the judge ruled the plaintiff failed to allege facts supporting his assertion that the dealership was an agent of GM and under its control.
According to the judge, the " plaintiff's allegations fail to demonstrate privity of contract between him and GM ," therefore the implied warranty claim fails.
The judge did let pass a claim for breach of express warranty, and because that claim survived so did a claim concerning the Magnuson-Moss Warranty Act. A claim against GM for common law fraud didn't get far as the judge ruled the allegations don't adequately plead the automaker knew about an alleged transmission defect.
In the lawsuit, the plaintiff argued GM knew about alleged problems with the trucks due to internal tests and customer complaints. However, the judge said courts " routinely reject generalized allegations about 'testing' and manufacturer 'analyses' made in support of finding knowledge of a defect.
The judge also wasn't impressed by arguing complaints made by customers automatically mean the automaker " knew " about alleged problems with the trucks. The judge found most of the customer complaints were filed after the plaintiff purchased his truck, so the plaintiff can't say GM had knowledge of alleged problems prior to the purchase of his truck. As for internal records held by the automaker, the judge said any allegations GM knew of alleged defects are " conclusory and insufficient because they do not plausibly allege that GM "knew of the defect prior to the time it distributed " the trucks.
The judge also dismissed a claim of unjust enrichment because under Florida law, " the existence of an express contract between the parties concerning the same subject matter " precludes a claim for unjust enrichment.June 20, — GM 8-speed transmission problems have caused a proposed class action lawsuit that alleges GM's 8L90 and 8L45 transmissions shake, shudder, kick, jerk, buck and experience problems during acceleration and deceleration.

The 8-speed model 8L90 and 8L45 transmissions allegedly malfunction whether a vehicle is decelerating or accelerating, causing drivers to pay expensive repairs for problems General Motors allegedly knows about.Mali oglasi
But even with alleged knowledge of transmission problems and the cost to customers, the automaker continues to market and sell the vehicles. GM owners complain about transmissions that shift and engage harshly and can leave them stranded on the roads at any time.
