Same as others on here with the vibration or "driving on rumble strips" problem.

They did a transmission flush which so far has worked so I am satisfied at this time The service manager was very responsive when I just brought it in. The service department was much more responsive than the person I talked to on the phone who said she could give me an earlier appoitnment and she could not guarantee when it could be fixed if I brought it in when I requested an earlier appointment.
#Chevrolet transmission lock up shutter update
Update from : I took my truck in instead of waiting for appointment. I am trying to be included in current class action suits already filed for this. It will cause further damage but they don't seem to care!" I contacted service dept at dealer and they said they know what it is but could not give me an appt. It has begun to shudder constantly when accelerating or decelerating. The dealer had used it as a service loaner and it had 3,000 miles on it. I have a 2018 Chevy Colorado that I bought new from dealer 8 months ago. With some easy digging Colorado 2018-2020 are as well equipped with these transmissions.ĭue to how late I am coming into this issue realization I don't believe a simple transmission fluid replacement will be a fix. There is an ongoing lawsuit in California on this defective transmission, all reporting the same issues that I have read on this forum. The 2015-2017 models were equipped with the transmission model number 6L50.

I am less than 20,000 miles away from the end of my powertrain warranty.įor all knowledge, I did my research and have all my ducks in a row which I would like to share. During my drive today it has gotten even worse with a jerking feeling while on cruise control to maintain speed as if it is having a hard time getting into gear and staying there.The dealership service department opens up on Monday so I will keep everyone up to date on this process. I took the truck to firestone for a potential balancing issue which turned into them telling me it is something with the transmission or torque converter. It will happen during any acceleration periods or in 5sec or more intervals at speeds between 25-80mph. Within the start of this year, the shudder has gotten worse and more consistent. Occasionally once in a blue moon in the next year, I would feel the shudder or rumble strip feeling and chalked it up to potentially rough roads or tires losing grip. Immediately I expressed my concerns about a potential transmission issue to my father and we both decided it was potentially just due to it being a brand new vehicle.

About 3 days after buying it I noticed the lurch or jerk during stop and go actions. This truck is my baby! The truck was bought with a starting mileage of 225mi due to dealership transfer. Never have I bought a new vehicle of my own, always used. $450.00 problem solved.I bought my ZR2 in December of 2018. The fix - the dealer pulled the vlave body and took it to a machine shop where they reamed out that port, installed a steel insert, so now the steel ball in the tcc solonoid can seal off on steel surface. aluminum? Any way, the steel ball starts to peen away the surface of the aluminum valve body, when the fluid gets warm (that's when mine did it) the fluid thins out some and leaks past this "improper" sealing surface and it messes with the line pressure. See, the tcc solonoid is sort of a proportioning valve, it has a steel ball that opens and closes and that steel ball seals off on port in the aluminum valve body. The problem was two fold, part of the problem was the tcc solonoid, the other half of the problem was the port on the valve body where the tcc solonoid seals off. He picked it up on his scan tool right when I said it was going to pop out fo OD. As we were driving I told him what exactly happened and when.

No trouble codes were set, so I took the dealers tranny guy for test drive, he brought along his tech 2 scan tool. My last truck was a 99 1/2 ton 4.8L with the 4L60E, I had the same problem.
