2015 Corolla CVT software update service bulletin
Hello - I know this topic has been discussed ad nauseum and I've read through as many of the posts as I could find but I haven't been able to find the answer I've been looking for. My goal is to avoid EVER taking my car to the stealership if I can.
So what I seek are what folks have experienced as "symptoms" of a CVT that actually needed the update. E.g., someone who had "symptoms," did the software upgrade, then noticed a distinct change in the CVT's behavior.
The symptom I have happens about half the time when I start to accelerate from a dead stop or a slow rolling stop. The CVT seems to not "catch" (if that makes sense) as I step on the gas. The engine very briefly speeds up a little, then the transmission "catches" or engages after that very brief period of not catching. My question to those more experienced that I am: Is this an issue that you may have had and if so, did the software update fix it?
I know some might just say to me, "Go get the update - it's free." Yes, I know that but the stealership in my area has some bad feedback with some people I know. I hope to avoid ever having to go there for anything. The one and only time I went there was to buy replacement windshield wiper blades. They sold my the wrong ones.
Thanks for your patience with me bringing this up again and I appreciate any input!
