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.

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.
