1999 mazda protege

I do recall Mazda having problems with trannys. I will look up any tsb's or recalls on it when I get to my computer.

Is the OD light and check engine light on? If not, check engine/ transaxle mounts, if yes, there is a bulletin about moisture in the tranmission range switch, unplug it and check for moisture or corrosion. If found have a Mazda dealer replace the switch, if it's not installed right, internal damage to the transmission will occur.

The check engine light is on and I took it to Auto Zone but the code was for a O2 sensor. I will have someone check engine/transaxle mounts. I will also check for moisture/corrosion in transmission range switch. I have my fingers crossed that this isn't a major issue....thanks.....Les

let us know

Finally back in town and first thing I did was to replace burnt out/missing warning bulbs in instument cluster(seller had apparently removed, hmmm) and I have a flashing O/D light. Check engine light no longer on after replacing air filter and cleaning map sensor. I had my 1999 mazda protege scanned for codes and it revealed P0750 (Pressure Control Solenoid Malfunction). From reading various Mazda forums with people with similar probems this seems to indicate a bad EPC solenoid. What do you think? I think this is a project that I may be able to tackle if so. Any advice is greatly appreciated. Les

If it is the EC-AT Solenoid, it is located on the valve body. Drop the transmission oil pan, after draining and there it is.

Motor and transaxle mounts can be checked by firmly setting the parking brake, putting the car in gear, and watching the engine/transaxle for excessive motion as the RPMs are raised to about 2000. Stand at the side of the car while watching. Block the wheels for added safety.

I don't see a P0750 for this make and model. I see a P0751 which is shift solenoid "A" malfunction-stuck off. P0752 is the same, except 'Stuck On'.

Thanks......is was the solenoid.....dropped the pan, replaced the solenoid and it is shifting like it was new! Thanks for yr reply!

Our pleasure.

i have almost similar problem with my 1998 mazda protege lx 1.8 engine on flashing od off light. mine will usually occur when it during highspeed or during uphill driving but the flashing will turn off as soon as i stop and shift it back to park position. i already replace the throttle position sensor on this car but still the flashing occur once in a while. is the epc solenoid same as the so called ec-at solenoid? how many solenoid do i need to replace?

I would start with the EC-AT solenoid poch

is the ec-at solenoid still located under the valve body or i need to remove the valve body to pull it out? i already change the at filter on this and fix the wire inside. i was hoping that it was just a problem on my tps but still it happened this afternoon after i replace the tps i was driving up the access ramp and when im going down the road the flashing light turns on. and it feel like it doesnt go to overdrive gear.

You should see it after draining and dropping the pan.

my mazda protege is 1998 mode this is an LX 1.8l. according to a mazda dealership here in edmonton, this type of model was release only here in canada. this is the VIN number of my car: JM1BC1422W0186375. can someone help me the right part # of the shift solenoid A and also the epc solenoid? do i still need to pull down the valve body to remove it? or it can be easily puled out. i need to order this solenoid as soon as possible that is why i really need the right part number of it.

You can get the right part # from the dealership much quicker than we can, and you wouldn't be charged international phone rates, either.
