| from the sounds of it i'm having the same problem as a few others. 2000 mazda 626 4 cyl. auto transmission. my transmission will shift out of overdrive and back into over drive rather hard when i'm maintaining speed of about 50-60 miles an hour. if i take over drive off and slow down to about 40-45 the problem goes away for a little bit but it'll start doing it again after driving around for a while. the problem doesnt happen untill the car gets warm and has been driven for about 20-30 min. the check engine light came on and i had them read the code and it came back trans range switch output high.i went to the dealer ship and paid and ordered the transmission range switch so i'm hoping that it'll fix it. does any one have any advice or helpfull tips for installing that switch. i'm a back yard mechanic and don't have a lot of fancy tools but it's my only car and i need this problem fixed. please let me know if you guys can think of anything helpful to me. thank you guys | |

Forgot to add if i have the overdrive on and force it to drive by giving it gas the overdrive off light will start blinking and if i am driving down the road with the overdrive on and come to a stop it will jump out of gear when i get to about 5 km/hour my wife also added the radiator fan seems to be coming on alot more than it used to |

Replying to: eharing (Dec 04, 2007 4:20 pm) 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

| I have a 2002 Mazda 626 been driving it a year the car runs great,but the other day the car started jerking felt like the transmission.The Overdrive light comes on evevery time it jerks could someone please help me. | |
| 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? | |
| I have a 2000 mazda 626 that starts just fine but when put into any gear (even neutral) will not move at all, wont roll, wont go anywhere. Any ideas what it might be? Thanks! Marsha | |

Replying to: mkmvette (Sep 24, 2008 5:37 am) 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 David
