2001 Hyundai Accent 6 cyl Automatic 108, 00 miles
In 6/08 I had the input/output speed sensor replaced in my 2001 Hyundai Accent. The symptom that I reported to the dealer was that the transmission felt like it was slipping. For a couple of months my check engine light has been going on/off followed with the issue of not feeling like my gears are switching when I accelerate. I took it to the mechanic, had the code read (P1529) which was a transmission control module. They looked online and saw that the common problem with this code and my car is the pulse generator, otherwise known as the input/output speed sensor. I gave permission for them to do the work, they got in and saw that my input/output speed sensor was very corroded and damaged.
Here is my question- how is this possible when I only had it changed 8 months ago? I live in an area where it is fairly cold in the winter time- could this have sped up the corrosion? Or is it possible that Hyundai didn't change that sensor but charged me for it anyway last year? I had other things done on that trip (transmission flush, belt changes) so at the time it was just another thing on the invoice and I didn't ask a lot of questions but now I am wondering.
Thank you for your advice!
