One of the most common problems with the GMC Acadia is when it throws the P0700 trouble code. A trouble code is a code thrown out by an automatic transmission whenever it detects that there is an issue going on. In the case of the P0700, it is a general code. This means that it should be accompanied by some other code that should tell you the specific problem. It is and OBDII code and not just GM code.
Acadia P0700 Code Explained
If you are scanning your vehicle right now, you should be looking for a second code that tells you what is actually wrong. Think about it like this.
- P0700 Says– “Hey there’s something wrong with this transmission.)
- The Next Code(s) Say– “I’m the actual problem going on with the transmission. I’m what you’re looking for.”
The code will trigger the service engine soon light and may put the vehicle into limp mode. If your vehicle has gone into limp mode, it won’t come back out until the computer detects that everything is operating within normal specifications. Here’s more on what causes limp mode or how to fix limp mode.
GMC Acadia P0700 Causes and Symptoms
Since the P0700 doesn’t indicate a problem (it indicates that there is a problem) here are some common problems that will cause the code to be thrown, as well as some of the more common symptoms that something is wrong with the transmission. If you feel there might be something wrong with the transmission, check out GMC Acadia transmission problems. There’s way more on problems with it there.

What Does a P0700 Code Mean?
The code could mean any number of problems with the transmission. You may need to have the vehicle scanned further to figure out what is exactly wrong. Does the vehicle feel different? Or is it a situation where you wouldn’t know anything was wrong if the light wasn’t on.
Before you take it in to be looked at by a mechanic, you should at least check and make sure that the transmission isn’t low on fluid. If you have felt a change in the way the vehicle has been driving, make sure you know the signs of low transmission fluid…
You don’t want to end up spending a ton of money on taking it to a transmission repair specialist to find out that it could have been fixed just by adding some transmission fluid.
How to Check for the P0700 Code
The easiest way to check for any trouble code with a vehicle is to get a OBD2 scanner. They are cheap and worth their weight in gold. Otherwise, you can always take your car to the nearest discount auto parts store (Autozone, NAPA, etc..) and they’ll be happy to go ahead and run the test for you.
Remember, once you find the code, it’s not time to stop scanning. Let the scanner tell you all of the trouble codes that the vehicles ECM has and google them, just like you googled this one.
What To Do, or What Your Mechanic Will Do
The first thing that the mechanic will do is plug in their OBDII scanner and see what code accompanies the P0700. As stated above, it can be anything. But, it’s often thrown when there are shift solenoid issues.
After that they’ll go ahead and clear the code and take the vehicle for a road test. This is normal. They want to recreate the problem. If it was a one off thing, there’s no reason to replace the part yet. If there is a real problem, the code will almost certainly throw again immediately.
Before you take it in, make sure that you check the transmission fluid. It’s also a good idea to go ahead and have a look at the fluid itself. If the fluid is a rough color, or worse you find metal flakes in it, that can be a sign that the transmission is going out.
Here’s how to tell what the color of your transmission fluid is telling you.
The Code is almost always accompanied by another code. There are vehicle specific trouble codes and there are codes specifically for your manufacturer. Good luck fixing your issue.
