Question about 2000 Mazda 626

Open pressure solenoid?

When driving over 60 mph on the freeway, the rpm dial jumped and the car lurched forward. It was like the car was searching for a gear or down shifting. I was told that the pressure solenoid circuit was open and would have to be replaced. I had the work done, but when I test drove the car with the mechanic in the car with me, it did the same thing. I left the car with them again so they can figure out what is wrong. Does this mean I need a new transmission? I only have 46K miles on the car and I am the original owner.

    pressure solenoid for my transmission. I do not know the trouble code, but was told that the solenoid was open.

    I was told today that the PCM (power control module) must be replaced. The solenoid cannot be grounded because the computer is bad? Does this sound right?

    there are more than one shift solenoid, you need to have the electronic trans trouble code to figure which one is the problem solenoid.

If the shop ran a test that coded the pressure switch they should not charge you for replacing a good part with a good part. If the part is regulated by a vacuum line, the shop should check the vacuum source. You may be alright with the shop because they tried to fix only what was wrong instead of the whole transmission.
This to me is a good sign. At 60 you are in top gear and/or overdrive. This limits the search to an area inside the transmission.

    I looked up the Mazda PCM and found there were recalls and problems for this part through several years and model lines. Within the 2000 model year there was a recall for the MPV version and the recall number was 86003. The Mazda recall line is (1-800-222-5500). Since Mazda uses similar parts in different products you may get factory help. As for reprogramming, it is not impossible for a dealer to do update programming when your vehicle was in the shop for something else. You should also ask if the PCM set a code and what that number was. Then call the factory number for help on this.

The pressure control solenoid is a electronically controlled valve inside the transmission. With that low of mileage you more than likely have a bad connection at a plug in Or some other type of wiring issue. It is possible that the solenoid is bad, even less likely a PCM (computer). You should not need a new traqns unless it has damaged somthing internally, but I doubt that. Good Luck

Shear coincidence. You have a transmission problem. Doing 60 MPH your RPM's should be around 2000, Usually a little less. One of you has a heavier foot than the other.

Ford code P0760


The code is for shift solenoid, this can include the fuse and relay which should be in the power distribution block under the hood. it may also be debris in one of the passages behind one of the solenoids. There may also be a ruptured/damaged seal to the overdrive clutch pack as well. Road test with pressure gauge and see what the pressure does at each shift point.

Don't know the issue

But that is the transmission coming out of gear

Not a good thing

I wouldn't drive it until a trans shop checked it out

Could be just torque converter lock-up (TCC)
