2002 Hyundai Matrix transmission problem. While driving the engine check light comes on and I am unable to kickdown to overtake. Whenever, I try to drive from a complete stop, the car seem to be lazy. I discovered that if I switch off the car then start, then switch off a second time then start, the check light comes off. I am then able to drive and kickdown as usual until the engine check light comes back on. What can cause this problem and how can I fix it?

swap w/rear radiator rear doesn't require fluid.

Your ABS likely has a very dirty reluctor (can happen if the teeth get mud or brake dust in them) or possibly one of your speed sensors is starting to weaken and is close to failure. The proper diagnostic sequence is to have the trouble codes pulled from ABS and Engine modules and determine what the computers SAW when the lights were turned on. Most likely based on description, your ABS will have a speed sensor code, and your engine and/or trans module will have a transmission related trouble code. Very few transmission codes are things you can service at home, usually youll see solenoid or gear slippage codes...mostly those require internal repairs that often require removal of the valve body or rebuild of the transmission.
Make sure you check fluid level, that is the most common cause of transmission slippage codes, however if fluid is full, it indicates that unless the fluid has failed completely, you may need transmission repairs.

Eh! I gotta google too. :) The Ecu computer controls so much on these vehicles these days that the dealers aren't equiped tofix their own makes.. It is possible like the other post sai, that there is some form of bsd connection. I figure the computer controls the information highway and keeps the operator informed on the happenings. If I can suggest looking at the transfer case for any electrical that could be talking to the computer Or possibly a sensor that is poorly connected. Is there a particular time or condition like rough roads/off roading or any thing else you can narrow it down to? If you live local to riverside or Mira loma, I would be more than happy to have you drop over and work together on this. I'm retired and home 24/7 and need something to do. Won't cost, a mechanic at a shop would so just let me know. I have a few ideas we can then discuss. It would take a ck list to cover it on here. My name is Ned @909-630-3192. Nothing to lose. good luck and feel free to call.

One reason for that light to come on is that the gas cap is not on correctly or has become defective.

the codes need to be pulled on the car first, Autozone does this for free. Check your local stores
