One quick question: Does the O/D light "Flash" when on extended highway trips?
If it does, you might have a "known" Mazda Service Issue.
I have a 1998 Mazda 626 4 Cyl Automatic and for some reason if I am Driving at 70 mph and let off the gas pedal my O/D Light Flashes and continues to do so until I stop and turn off the car, let it cool for about 10 minutes and then restart it again.
However while I am driving with the O/D light flashing (at lower speeds) I experience very hard switching in gears. After a full stop, when I start up again the transmission will shift into second with a bang then into third with a milder thump.
However this does not happen every time I drive 70 mph (Usually after an hour of highway driving.)
I spoke with a guy who rebuilds these transmissions. He said that when the O/D light "flashes", it is caused by a malfunction within the computer or a minor defect in the transmission.
When the light goes on, it enters a Fail-Safe mode… (the EPC solenoid opens up and brings line pressure up to 'max') ... the only catch is it raises the fluid pressure well beyond normal specs (it goes from 100 to 400 PSI).
It is at this time where you get your major failures. (Mazda switched the Automatic 626 to OBD II around the 1996 model year, so if you have a '96 or later, you'll need a full-fledged OBD II-compatible scan tool.)
A Mazda Technical Service Bulletin exists for some 1999-2001 models. TSB 05-005/02 deals with one specific circumstance: "After extended highway driving, the O/D off light is blinking and code P1783 is set (excessive ATF temperature). Occasionally there will be overflow through the dipstick tube and harsh shifting. Mazda's recommended fix is to replace the radiator and to install an auxiliary cooler for the transmission."
It sure can not hurt to tell your mechanic to examine the Mazda Technical Service Bulletin 05-005/02. Keep in mind that once your car goes in safe mode, your transmission fluid will get burnt up real fast. A transmission cooler cost about 40-50 bucks, and will extend the life of the poorly designed Mazda/Ford transmission. You will need to replace your transmission fluid during the install (if burnt) and read the directions on the cooler to adapt for any additional fluid.
Search on the internet for a Hayden Transmission Cooler, either Hayden 404 or Hayden 679... I prefer Hayden 404 because it has bigger piping than the 679 which doesn't restrict tranny fluid flow (Some use B&M Super Coolers).
Some people also recommend going with a synthetic transmission fluid (Supertech 2000 synthetic fluid for cheaper alternative).
Some people have also claimed that by using Honda's transmission fluid (Dexron I instead of Mazda's Dexron III). The thicker Honda Fluid w/ Honda's special additives have caused a rebirth to their Mazda transmissions.
You can also consider installing a Tranny Temp Gauge so that you can see the difference the cooler makes (and know when to stop prior to an transmission overheat.)
I would recommend printing out this and showing it to a trusted mechanic.

what a coincidence my car just started running rought and the engine light was flashing on and off when it was switching gears. Meaning when I hit 40 and then 50-60. Had my oil changed to day at monroe and the mechanic just driving it said it was misfiring and it was because of my wire kit. I just had a tune up not even a year ago and when he showed me the middle plug that is on the thing the oil goes into, it was white and not catching the sparks from the plug. So I would have your wire kit and plugs checked if they are both fine I was told it can be injector or your coil. I have a 99 mazda 626 lx. I am sure it will probably be your wire kit especially if the are the duralast brand purchased from auto zone. Hope this helps
#2434 of 2547 1994 Mazda 626 LX Overheating
Oct 18, 2008 (10:09 pm)
I am at the end of my rope with this problem. Let me start by letting you know what I did do to try to fix my problem.
I have changed both fans, cleaned and flushed the radiator, bought a new radiator, both of the radiator caps have been changed, I changed the thermostat, change every possible hose that I could find on the car, change the water pump, there are no leaks and if I accelerate in the car the gauge goes to the cool side. After the car was inspected the engine light came on and the car ran rough. I changed the sparks plugs and that took care of some of the problem but not all, the car still runs hot, the gauge goes to the middle toward the hot side. I have tried everything that I know to do and the hot problem is still there. All of the parts are new, so could it be something internal. What could I be missing? I have also changed the Universal Catylic converter. Please advise me on what the problem could be. Thank you for your help in advance.

The chat opens at 8:45 pm ET and runs until 10 pm ET. I hope you're able to join us tonight to meet and greet with your fellow CarSpace members!
See you there!
#2436 of 2547 Need to find thermostat on 2002 V6 HELP!!!
Oct 23, 2008 (12:10 pm)
Hey , I'm needing to check the thermostat on my 2006 V6 but don't know where to look. I need to know how to get to it and remove it. Can anyone tell me and hopefully post a pic or link? I'm new to working on cars so please be direct.
The problem I am having is that the heat blows cold when at idle and the temp gage is all over the place. Heat works fine when accelerating but at a stand still, nada.
Added coolant but problem persists.
P.S. Should there be more than just a few ounces of coolant in the overflow? Also, when I remove the cap, there is none showing at all. Should I be able to see some? Maybe I did not add enough.
#2437 of 2547 Stalling
Oct 28, 2008 (4:11 am)
I have a1994 626 hatch, i bought it 13 months ago, it stalls when turning right, when the fuel is low, the more i accelerate ,the quicker it stalls, i've asked several mechanics & none seem to know what is wrong, up until recently, so long as i kept fuel level above a quarter it was ok, but now it's doing it even with plenty of fuel, any advice would be appreciated
