Check Engine Light?

I got a transmissions flush done about 6 weeks ago now, since then the tranmission has been acting funny when I try to accelerate uphill it won't go into gear and until I take my foot off the gas and then replace it the car seems to fall into neutral. I took it back to the place I got the flush and they said it was overfilled by their tech so they drained 1 liter of fluid. The problem didn't get better so I took it back again, the place which I won't mention (Canada wide service center) told me to take it to a transmission specialist. I have a appt for next week but in the meantime the check engine light came on yesterday and the O/D light is blinking. Have any ideas on what the problem maybe? It seems to be intermittent to a constant thing.

Hi
to answer your question a scan was done and error code found in shifting between the 3rd and 4th gears. I guess they are going to remove the transmission to have a look?

My check engine light came on. THey told me that it was running lean.

How complicated is replacing the ECG valve going to be? I want to know what I should prepare for as far as time and money. And does this valve have something to do with car performance going up hills specifically? My car seems to have trouble power wise when going up hills and the check engine light comes on when this occurs. Someone told me it is the ECG valve that is causing it to occur. Is this right?

About 2 months ago I purchased a used Mazda Protege from a family friend. She had everything on it safetied and brought the car into Mazda for an engine test where they said everything was in really good condition. About a month after having it, the Check engine light came on while I was driving. Just to make sure, we unplugged the battery so it would reset, the light went away, but came on again in about 2 weeks. The car sounds great, starts great, all the fluids have been checked and double checked, the filters were just replaced before I bought it so is this just a sensor problem or should I be spending the money to take it in and get it checked?

I would but I live in Canada and we don't have an autozone here.

I will call around and see if I can find a place to scan for free and get back to you. Thanks

You can also start by performing a quick visual inspection, look to make sure that no connectors are disconnected under the hood, also make sure that the gas cap is tight and the sealing surface is clean. Let us know how it's going eh.

Well so far, since unplugging the battery and reseting everything, the engine light has not come back on. I started a Trip to record my mileage this time and so far I've driven 379 miles. However when it does come back on, like it did the previous times I resetted, I will take it in and get back to you guys. Thanks

I just bought this car off craigs list. I believe that was my first mistake because the engine light came on only 3 days after I had the car. I took it into the shop and they hooked it up and told me that the light was on because the last owner put bad gas in and a sensor in the cadilac converter went bad. About a week later I was sitting in my car with it running waiting for my sister to get off work and the o d off light came on. I cut my car off and back on and it went away. Do you think that this is a problem and do you know if it can be fixed or if my car will break down soon?

This is also an issue on the ford explorers. There is a solenoid in the tranny that sticks. Causing this light to come on. When you shut down and restart it clears and seems fine. Not so in many cases have the tranny serviced and see if this clears the problem up New filter and fluid is always good on a used car. If the solenoid it bad have it replaced or you could cause more severe transmission issues.

Let me know how it goes and we can try to get it fixed for you.
PS: by the way I own ford explorer that had the exact same issue. Just needed tranny service

I am now at 600 miles and the Check Engine still has not come on after I reset it. Today I did however go to Mr. Lube to get an oil change. They also check everything and the only thing that they noticed was my PCV Emission valve was really plugged. So they replaced it for 12 dollars.

Could it of been the PCV valve being plugged causing the engine light to come on?
