CVT shifting issues and new TSB PI1309

91 posts in this topic

I have previously posted about a concern I had about the CVT sometimes not resetting to the lowest ratio at a stopped condition, this made it very sluggish pulling out. I contacted Chevrolet Customer service on the forum with my concern and Jasmine replied. She checked up for me and found there may have been a TSB for my issue. She contacted my dealer and they called me and set an appointment for me to bring it in to be checked.

I took it in and they found out it did need the TSB TI1309 to be performed to reprogram the TCM. They completed that this morning and so far it seems to have cured that issue and the transmission does not seem to be as jerky at low speed either.

So if you have these issues I would have my dealer check on that TSB.

Just noticed on my dealer printout it is listed as TI1309 and PI1309....

Are you sure about that TSB number? I have looked everywhere and can't find it anywhere.

Finally! I knew there was a problem with the CVT's with all the posts of the same problem of the low gear not engaging. So now the recall and I'm glad to hear that the problems have been cleared up by this warranty recall service. The design of the 2014 CVT is fairly new with an auxiliary gearbox attached to the CVT. Hope this works out well for all of you with the described problems!

There is no recall, its a TSB. You will need to ask your service advisor about it or do like I did and have the Customer Service Rep on here contact your dealer with the information.

I have been experiencing this exact problem. When coming up to a complete stop, it hesitates to drop to the lowest gear. When taking off, it feels horrible. I have taken it in a few times and was told that it was "normal operation". :(

Printout the above post by Angrybird, and take it to your dealer, or contact Chevy Customer Service here on the forum, there is now documentation that this problem does in fact exist, the dealership needs to be made aware.

I have taken a few road trips and been driving around town quite a bit since the software update and it works great. Its been in the upper 80's and Lower 90's the last few days and using the AC it still has plenty of go off the line...

And I do believe it has helped my gas mileage too.

That isn't the issue I am referring to. Not sure what yours is but its not the same thing.

Did it start then or just recently? How many miles do you have on yours?

I have an app tomorrow to get my cvt reprogrammed aim tired of it jerking and shuddering on takeoff it has even dies a couple times at stop lights called on star of course no stored codes or check ending lights so I'll get the update done and see if that fixes it . My ac doesn't seem to cool the car either so they are going to look at it too .

Let us know how it goes, it seems everyone is happy with the CVT fix. Did you have the a/c recall done? or is this the first attempt to fix it?

Good luck!

I had the CVT reprogram done a week ago. So far so good. But I am having a terrible time getting them to fix the AC even though the car is under the recall. They did the limit switch replacement and the rewiring but that's where they stopped. They refuse to replace anything else as they say it is now operating normally even though it still cycles on and off going down the road and blows warm at idle. i have had it to them twice now.

I am getting ready to take it to a different dealer for a second opinion. i also found that the door that dictates where the air goes is not closing all the way and cool air is being directed to the floor. i reached out to Chevy Customer Care on here but have not heard anything back yet.

My wife wants me to just cut our losses and get rid of it but I really like the car just starting to get a little worried that long term it may be trouble.

Update was on my way to my 745 am appointment cruzing down the 4 lane road at 65 mph when the car starter jerking and bucking then it just died I coasted over to the side of the road tried to restart and nothing it smelt like something burnt up . Called on star and did a diagnostic check and guess what they said everything checked I said then why won't my car start anyway had to be towed to dealer they worked on it for two hours . Turns out a loose bolt on a ground caused a coil to burn out and that's why the car was jerking and bucking . So update to trans was not done they think that's why the car was doing what it was . Sounds weird but he trans and ac seemed fine driving back home .

If you hear nothing back from Chevy Care here, then use the info below. Keep us informed.

From the owners manual, pages 13-1/13-2:

"If after contacting a member of dealership management, it appears your concern cannot be resolved by your dealership without further help, in the U.S., call the Chevrolet Customer Assistance Center at 1-800-222-1020."

Some of these dealers are just a**holes, and need a boot once in awhile.

I knew of a recall on the AC on the 13's but is there also one on the 14's? Mine just started randomly blowing warm air while driving down the road, it's like the temperature door goes crazy. The fan changes tone and it sounds like the compressor cuts off.

Yes, some of the early 14's are covered under the recall. Mine is.

Is it a recall or just a TSB? Recalls have notices sent out, TSBs will only be done if an owner complains about that condition.

This is the way it is worded. My VIN fell under the program:

The customer satisfaction program is for the air conditioning system so it will provide a fix for your concerns about the intermittent cold air.
