Hello Ernie,
 
One quick question: Does the O/D light Flash when on extended highway trips?
 
If it does, you may have a "known" Mazda Service Issue. My 1998, Mazda 626 LX 4 cyl 2.0 had a very similar issue that happened only after driving at highway speeds for about an 70 minutes.
 
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.
 
Good Luck

#23 of 71 99 mazda 626 auto trans. trouble by 5ddjjh

Sep 20, 2008 (7:26 am)

it was suggested that i check for ablown fuse in my 99 mazda 626 w/ auto trans. the car suddenly quit shifting into gear and a check of the fluid reveals it is up to level and not burned. when you start the engine, the fluid level drops, indicating that the pump is functioning. My questions are 1. if there is a blown fuse, where is it located? 2. if not a blown fuse, where would the module be located that affects shifting?

Marsha,
 
           My daughter has a 99 626 automatic and it suddenly quit moving when you shift it into any posistion. In this case, it turned out to be simple. The transmission shift cable came loose at the transmission. It appeared to have lost some sort of retainer that attaches the cable to the shift lever on the transmission. It was a cheap and easy fix. Good luck

Let me make sure that I understand. You have a Mazda 626 with the problem of the transmission not shifting into gear? And is due to the shift cable coming off at the transmission shift lever, found under the hood located on the left side near the fire wall? If so, the problem is the same as I encountered. Initially to make mine work, I took ahold of the end of the shift cable and spun it 180 degrees, which caused it to lay tightly against the shift lever on the transmission. At that point there was nothing holding it securely other than the force of being rotated. I then took it to my local Transmission shop and he figured out some sort of retainer(that he made up himself) and unrotated my cable and reattached it to the transmission shift lever, all for no cost. Even if you needed to pay to have this done, any local, decent repair shop should be able to make a repair for a minimal amount, say 40.00 or less. I have said a lot, and hope somehow this helps.
