Guy's,
Background:
I have a 2013 Genesis BH Sedan R-Spec with 223000 miles. I had the hard shift we have all experienced or heard about. My transmission was so bad it felt like I had been rear-ended by someone other than Hyundai. I was forced to drive in manual mode through 5th gear. After that it changed gears as you would expect.
I was very frustrated because my car, despite the miles, looks like an almost new car and the engine runs beautifully. In fact, days before I made a plan to fix the tranny myself, I had the car over 140mph and she never hesitated for a second.
I did what everyone else has done and bought OBD code readers but none had the ability to talk to the car in the required way. I found the TSB on the solenoids and even though I am not a mechanic, I felt I could do the job. I also felt the tranny was going to have to be replaced from me screwing it up or it failing on it's on. Swapping the transmission out did not seem like a great plan as I might have ended up with another bad tranny like other owners have.
I was working for a Dodge dealership about this time and I asked the service manager to see if they could access the TCM in order to reset the transmission. I was told the scan tool and the car would not talk to each other. We had a Hyundai sister franchise close by so I went there and was told the same thing. Il don't understand why they said there computer would not talk to the car.
So I decided to try to fix it myself. I found the solenoids on Amazon and ordered them. I figured the car just might relearn how to shift on it's on with 2 new solenoids. I replaced the solenoids and the TCM module (I broke it) and put it all back together. All in all, pretty easy job.
At last I could drive the car without the hard shifting but I had a whole new set of issues. I am guessing the car kept adjusting itself to compensate for the failing transmission because it didn't seem to know when to shift. Several times it was stuck in a forward gear and would not reset until I shut it off and the cranked it back up.
I have ordered numerous scan tools that promised to reset the transmission but none did until....I found the Holy Grail of scan tools for us poor Genesis owners.
I hooked it up, downloaded the correct files and low and behold, it was all right there in the menu. I was able to actuate each solenoid and each one passed. I then chose reset to factory default and I went for a drive. I couldn't believe it, smooth as butter. Now, I bought the car with the hard shifting which was not smart, so I had never know this car without the shifting issues and this was amazing!
I was also able to release the damned parking brake as well. In fact, I went through and tested every component I could.
Word of advice, if you decide to go this route, buy a new TCM ( the TSB says to anyway ) as you are likely to break the very brittle TCM trying to get it out, I did. Also, be prepared as far more trans fluid is going to suddenly pour out than you expect.
I will try to answer any questions you have that I can answer. Youtube is where I learned most of this so please start there and watch as many videos as need to give you the knowledge and/or confidence to tackle this.
Here are the links to the scan tool, Solenoids and TCM. I am not an Amazon affiliate and will receive no compensation for posting the links. Also, you are own your own and should seek advice from a professional mechanic if you run into problems.
Thanks,
Jeff
