General Motors has announced a new Customer Satisfaction Program for certain examples of the 2021 model year Chevy Silverado 1500 and GMC Sierra 1500 to replace the eight-speed automatic transmissions in the vehicles.
The problem: in affected Chevy Silverado 1500 and GMC Sierra 1500 units, the eight-speed automatic transmission (RPO MQE) may have a broken reaction carrier ring.
The hazards: a reaction carrier is part of the transmission rotating assembly and is an important aspect of its operation. A broken reaction carrier could prevent the transmission from operating as intended. This problem does not pose an immediate safety hazard to vehicle occupants.
The fix: dealers will replace the entire eight-speed automatic transmission with a new one. These repairs will be performed at no cost to the vehicle owner.
Affected components: reaction carrier, eight-speed automatic transmission.
Affected vehicles:
- 2021 Chevy Silverado 1500 (with GM eight-speed automatic transmission)
- 2021 GMC Sierra 1500 (with GM eight-speed automatic transmission)
Next steps: GM will notify owners of affected vehicles and instruct them to make an appointment with their dealership. Owners can also use the contact information below to reach out to Chevy or GMC customer service with any questions or concerns they may have.
Vehicles involved in this Customer Satisfaction Program were placed under a stop-sale order on February 8th, 2021. These vehicles will be released from stop sale/stop delivery status once the repairs contained in the bulletin have been performed. This Customer Satisfaction Program will remain in effect until March 31st, 2023, after which point the repairs in the bulletin will not be made to affected vehicles.

I have a 2016 and a 2018 Silverado with 8 speed transmissions. Both were making growling noises and vibrating after only 40,000 kms. Dealer changed the transmission oil in both and now they are fine. Never had to do that with my other 8 older Chevy trucks.
you are good to go now until they are ready for the crusher and that trans.will be waiting for a guy that has been looking for a good one for a long time.
I’ve got 40 miles on my 2019 Silvy with the 8 speed tranny, never had one problem! You whiners are all trolls!
A whole 40 miles give it another 40 miles and circle back.
Lol go home, with your 40 miles
Need to fix the 5.3L Engine first!! You can’t go anywhere without an engine that runs. I’ve had 3 lifters “Collapse” on my 2021 Silverado with only 7k miles. The first time at 3200k. And I promise you they could care less about customer satisfaction. To bad it’s not still at the dealership, I would call them and have them just go ahead and do the Trans also. Knock that out of the way too!!!
Breaking news GM has called a lid on all further complaints about 8 speeds,complaints will need to be by e-mail only and they will circle back with you when the # of cuomo harassment complaints equal 8sp complaints.
Why doesn’t GM just use the ten speed in all the full size trucks? To keep using 6 and 8 speed transmissions is asinine.
I work for a GMC Chevy dealer and, after reading said “Recall”, apparently only 64 or so vehicles (by VIN) are involved. Enjoy.
2017 sierra with 8 spd transmission. Nothing but crap from day one, dealership closes it’s eyes to any problems, paid 3k for extended warranty. Stuck with an expensive POS. Just about had it with GMs BS. Pay so much money for a truck and get shafted.
How about the 8-speed in my 2021 3.6 Chevy Colorado?
Sold my 2017 High Country with the 8 speed do to hard shifts and no repairs offered, truck only had 27k miles. Went to a 2021 LT trail boss with the 10 speed and could not be happier.
I would do that myself if I hadn’t just bought mine 3 months ago. I’m not upside down or anything but i just can’t make myself buy another gm product right now. I miss my old ‘79 Silverado.
No problems with the outstanding ZF 8 speed in Rams.
I had a 2018 ZR2. I liked the little pickup, they could never get the transmission to shift right. When its cold, put it in reverse and it just sits there for 5-8 seconds before it moves. I traded it. Have 2016 GMC 1500, they went through and dumped all the original fluid and all suggested updates. Still not great, but better. My 2020 ten speed in my Duramax is flawless, 35K pounds combined while towing and it just as smooth as when empty. The programming on the tranny is exceptional. Why the 8 speed is such a mess is beyond me. More over, why they keep putting into vehicles is even harder to understand. That tranny causes GM more issues than anything else, by far. They apparently want to continue to fight over it, rather than turn the damn page and move on with the 10 speed.
Breaking news they are sticking you with a garbage trans because all there attention is on energizer bunny powered vehicles.
A long time friend of mine that has run a transmission shop since the 1970’s told me to stay away from any GM with the RWD based 8 speed automatic and that it was a poorly designed unit from tear down analysis sheets that he receives from training material. He has never steered me wrong before so I’m going to heed the advice and strongly advise from it’s purchase. He also told me the old 6 speed and newer 10 speed have a far lower incidence of repairs and warranty claims but that should be obvious by this point.
Too little, too late. I drove GM trucks for 25 years. My last was a 2017 LTZ with the 8L90. Shudder on the highway was unbearable. Despite having spent an additional $3000.00 for extended service plans and being within the drivetrain warranty period, they flushed my transmission as a fix and would do nothing else. I traded that truck off three months ago and will never, ever purchase another GM product.
Have the Mobil 1 blue label put in. Fixes any shuddering issues. If you drive it too long with the shudder you will damage the torque converter necessitating a replacement.
I’m not trolling!!!! Love my 2021 Silverado LTZ but don’t like the tranny
Dealer replaced the valve body on my 21 Silverado 8 speed a year ago. Has been great since
