I had the transmission on my 2000 Hyundai rebuilt by a large national chain a few months ago. The local Hyundai dealer reccomended them since they do not have their own transmission shop. At 154K miles, the car is definitely out of the manufacturers warranty. Recently, the car has started to act up a bit, and I noticed that the 'Check Engine' light wasn't coming on anymore when I start the car. When I opened up the dash to replace the bulb, what should I find but an empty socket where the bulb was supposed to be. When I put a bulb in the empty socket, I was not at all suprised to find that the light was continuously lit. Does anybody know if the dealer can determine how long the light has been lit (OBDII)? If it has been on since I got the car back from the transmission shop, and if the dealer's mechanics determine that the transmission shop was at fault, do I have any case against them? Unfortunately, the transmission only had a 6,000 mile warranty, which I have long since out-driven. With this particular transmission chain, I have heard that the warranty is worth less than the paper is printed on, and that they have more lawyers than mechanics on their payroll. Something tells me that I may have to eat this bill, however high it might be. I consider myself to be mechanically compitent, although newer vehicles (OBDII) are beyond me, due to the hundreds of sensors and whatnot under the hood. Even with the factory service manual, I am at a loss when troubleshooting the check engine light, because I would need propriatary tools that cost nearly as much as the car itself does. If anybody has any advice for me in this, I would appreciate it.
