Running problems are an engine problem, not a transmission problem. Even if there is a problem in the transmission, a flush isn't going to fix a mechanical problem. Transmission flushes rarely solve a problem. They are done for preventive maintenance on cars that have a history of developing transmission problems.

We don't get involved with costs here because there's way too many variables. You don't even know what is wrong yet or what is needed.

I've never heard of a new-car dealer that couldn't handle transmission repairs on the brand of cars they sell. They have specialists who receive regular factory-sponsored training and updates as a requirement for having the franchise. They have access to service bulletins and a hot line for help diagnosing elusive problems. The dealer is the top step when no one else can solve a problem, but their remedy could simply be to install a rebuilt transmission.

Independent specialty transmission shops eventually get the same service bulletins, and they are not bound by the limitations manufacturers put on their dealers' service departments. The aftermarket parts suppliers are real good at developing repair parts that are improved to solve recurring and common problems. The dealers are often not allowed to use those improved parts unless they're approved by the car manufacturer. The people at the dealership my elect to send you to a transmission shop when they know that shop has more to offer you when it comes to a lasting solution or a better value.

This sounds like you have a clogged cat this guide will help confirm the issue.

What do you mean by running hard?
Wta is the idling speed?
Have you checked for trouble codes?

Hi,

Since the security light is flashing, my first question is if the reprogramming of the key was done correctly. That light should be off if the car recognizes the key. Have you spoken to the person who did it for you?

Next, what really needs done is to have the computer scanned to identify diagnostic trouble codes specific to the anti theft. Here is a video that shows how it is done:

I realize most people don't own a scanner, but often times a parts store will do it free of charge. Often times they will either rent or lend one to you if the vehicle isn't running or safe to drive.

I mention having it scanned because there could be many things causing this to happen. There really isn't a reset or anything like that other than if it is done with a scan tool capable of communicating with the vehicle's computers.

I mentioned if it was done correctly because there are many things that can be causing the problem. Not trying to be confusing, but if you look at the two pics I attached, you will see only a few things that control the anti theft. Without a diagnostic trouble code, it becomes a guessing game and I wouldn't want you to replace parts that are good. In all honesty, my first suspect is it needs reprogrammed.

Please feel free to ask questions.

Take care,
Joe

A green key is what you need. Did this just happen since the key was replaced?

Joe

Replace the engine coolant temperature sensor. If it is causing a faulty reading I have seen it cause random misfires. Let us know if that was the issue or if further assistance is needed after.

Hi,

I hate to say it, but it needs reprogrammed to recognize the new key. Have you spoken to the person that did the work the first time?
