"Conditions not correct for shift"

[gone]

Definitely get it checked out. Even if it's a "one-off" you'll create a record so if you have more problems after your warranty has expired, it might be covered. My HTC had no problems so I expect it's a DCT issue (DCT common to both Coupes and HTC) rather than a Coupe vs HTC issue. Good luck toronto365 and let us know how this is resolved.

OnStar Basic is free for 5 years. Doesn't tell you much.

Ya, it tells me via announcement through the radio once a month, that OnStar is limited. In 2014 we got a similar message BLASTED through the radio every time we started the car. Took me several angry phone calls to get the system removed from my car. It can be completely disabled remotely even though they swore it could not be. LOL

 

[Sparro]

I was wondering about that. Do you have to be a suibscriber?

Yes, you have to have an active OnStar subscription for the OTA diagnosis.

With issues like these , why not get it towed to dealer rather than have the C8 hiccup and dance around?

 

[toronto365]

Just got it back from getting PPF. Drives fine but still showing CEL and struggles to get into Reverse sometimes.

To the guys that have had DCT troubles (and hopefully since resolved), any recommendations on a west end dealership (Mississauaga/Oakville/Burlington) that is experienced with DCT issues?

OnStart just ran a diagnostic ...

TCM - Transmission System
P2746
The Engine and Transmission System is not performing as expected. An issue has been detected in the Transmission System that transfers power from the engine to the drive wheels. You may experience reduced power or shifting issues. If the vehicle is continually driven with the check engine light on, the emission controls might not work as well, the vehicle fuel economy might not be as good, and the engine might not run as smoothly. This could lead to future repairs. Service within 7 days

Mine was done at Applewood’s.

All the DCT issues I've heard about had a GM engineer involved. Any place you go to has that option, so it's important to go to a dealer that is trustworthy and has experienced techs. Hopefully Applewood's has/is both.

 

[toronto365]

Applewood couldn’t see the car til next week but Budd’s is looking at it now.

On my way here, it was skipping 2, 4 and 6 gears

@toronto365 good luck getting this sorted out. I am sure a lot of folks look forward to hearing what is happening with the transmission. Has to be frustrating.

Budd's did the DCT flush 3x as prescribed on Friday.
Took it home, drove well.
Started her up the next day, same issues reappeared on start up.
Took it back in this morning.
Chevrolet has authorized a new transmission, but it is on min 30 day back order

If my car was brand new and the engine and trans had to come out I would tell the dealer to put me on a short list for a new one, guess I don't trust dealers for major surgery

 

[AdC822]

Hey 365 sorry to hear that.

Good luck with that man!

 

[toronto365]

Update: New transmission is expected on April 26, directly from supplier

On my way to work there is a long downhill access route. I usually throw it into Neutral until I hit the light at the bottom. One time I accidently hit Reverse with the car still rolling and received the same message. Just happy the computer is smarter than me. Ok I'll get it out of the way. Everything is smarter than me...

Not a good practice to coast in nuetral. I'm sure the OM says it's a no no.

Not sure whether it robs the C8 tranny of lubrication while in neutral and coasting bu the other side of this is that it saves zero gas doing this.
