2017 Chevrolet Silverado: hesitation when accelerating

Filed Jan 29, 2020 · Transmission · MN

The transmission on this truck has not been right from the beginning. When starting in the morning it will do one of three things: surges and transmission skips, hesitate and then race or jump ahead, or chunk and thunk like it really doesn't want to go to work and shifts hard when it does. I keep asking when gm will take care of this problem and I keep getting the run around. I have brought it in 3x, have had diagnostics run, transmission flushed and of course it has not helped. I am now bringing it back to chevy dealer and now they say I have to do the next step according to gm which is put in a new torque converter. I bought a beautiful truck that runs like crap and I am very frustrated.

Truck down and upshifts hard. When slowing down for a car in front of me, when I get back on the gas, the truck has no power like it can't figure out what gear to be in. Makes a loud clunking noise with light acceleration from 1st to 2nd gear. There is major hesitation when trying to down shift no matter what gear I'm in. Problem needs to be fixed before someone gets injured. Been to chevy 3 times for the same problem and all they tell me is the transmission will learn how you drive. They also told me there is no new update for the transmission module so I'm screwed.

The 8-speed automatic transmission exhibits numerous issues. 1) when slowing down to under 10 MPH, as if you were yielding to traffic and then pressing the throttle to accelerate the vehicle, two issues can occur. First, the vehicle's transmission can hesitate between gears, providing no power to the wheels. Second, when vehicle does shift into a gear, the vehicle can lurch forward unexpectedly as if you were hit from behind. There is sometimes an audible "clank" when this issue occurs. This issue can prevent a driver from successfully entering traffic due to loss of instant power to the wheels. 2) during low-speed acceleration, the vehicle can hesitate between the first three gears, providing no power to the wheels. It has a similar feel to a transmission that was slipping. This can cause a driver to over-correct the deficiency in power to the wheels by applying excessive throttle and cause an accident. 3) when proceeding slowly in stop and go traffic, the vehicle can shift up or down suddenly, causing the vehicle to lurch forward unexpectedly. There is sometimes an audible "clank" when this issue occurs. This can cause the vehicle to strike the rear of another vehicle, in tight traffic, if the driver isn't prepared to apply the brake when the event occurs. 4) when driving normally, the transmission may hesitate to downshift when the accelerator is applied as would be necessary when trying to pass a vehicle. This does not appear to be gear dependent. The loss of instant power can prevent the driver from successfully overtaking another vehicle in the event they need to conduct a passing maneuver.

Engine hesitation, or misfiring. Jerking, or transmission shuttering when engine is at low RPM and on incline. (I.e. When traveling about 45mph and start up a hill, the RPM's are about 1300, and the transmission doesn't gear down, so it starts shuttering until you give it more acceleration than usual.) after dealing with this issue for nearly 8 months and 15k miles, I believe this safety issue should be recalled. Dealer originally acknowledge the problem but was unsure of the cause. After 5 repair attempts the dealer say they can't duplicate and the vehicle performs as designed.

Vehicle hesitation and surges in acceleration. This condition is a safety issue as it hesitates pulling into traffic, surges in acceleration have caused loss of tire traction on ice covered roadways nearly resulting in a collision. Dealers have acknowledged an issue but advise they are still waiting on a fix from gm.

Noticed after purchase that there is vibration like a bad tire 35-42 MPH. Vibration felt in seat,console and steering wheel 58-65 MPH. Transmission down shifts hard sometimes feels like being bumped from behind,it also hesitates and jerks after letting off the accelerator and accelerating again between 25-45 MPH. When accelerating it surges,jerks and stumbles. Sometimes when accelerating the transmission downshifts and hangs in that gear until you let off the accelerator. Under heavy acceleration there is vibration in the power train and the transmission seem noisy. At 25 MPH it shutters like the transmission is in to high of a gear under light acceleration. Returned to waldorf chevrolet where I purchased it and was told they balanced 2 tires and reset the road force,scanned transmission no codes transmission ok after shop foreman road tested for 21 miles no other repairs needed. Picked it up driving home noticed all the problems were still there and after inspection of my wheels noticed that the wheels were balanced still had the old weights still on the wheels with new weights also. Made another appointment this time to have shop foreman (rick) ride with me to show him what it was doing which we did and left my truck again. After 8 days I am told it was ready I was told they did a pico scope test and the driveshaft was being replaced then only tested it was ok. Checked run out on flanges all within specs. Found the right rear tire bad. They put steel wheel from another truck on and road tested with no change. They drove another truck and it rides the same. Even has the shutters on hard acceleration. Said they called gm tac back and they don't see a problem with this. Written documents be sent via mail. Made another appointment
