Showing the 25 model years where P0700 appears most; it is on file for 56 in total.
A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.

P0700 by make
The same record, one make at a time: the model years, bulletins and owner reports that name P0700 on that maker’s vehicles.
What it gets filed under
What owners said
Source: NHTSA complaint databaseOwners’ own words, one per nameplate, scrubbed of anything identifying. These are unverified reports filed with NHTSA — they are what was said, not a finding that it was true.
The codes that came up were P0700 and P0796 Transmission failure due to a stuck solenoid
We immediately did an at home diagnostic on the vehicle and were given the following codes: P0700, P0747
Diagnostic codes P0700 (Transmission Control System - MIL Request) and P2714 (Pressure Control Solenoid D Performance/Stuck Off) were stored
I contacted OnStar, which reported transmission control module-related diagnostic codes P0747 and P0700 and indicated reduced power/transmission malfunction
It had to be towed to the dealership and it was uncovered that his truck was throwing out codes P0700 P2732 which is a known issue with this truck, resulting in internal valve body hydraulic failure
46 manufacturer filings name P0700. Start with what the maker wrote down.
A code names the test that failed, not the part. A bulletin that names it is often a diagnosis someone has already written down — quote its number at the service desk.

What P0700 means
Source: SAE J2012 / OBD-IIThe transmission control module is asking for the warning light — the real code is stored on its side.
A stored code names the test that failed, never the part that caused it. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
Common questions about P0700
Source: NHTSA files and the OBD-II standardCan I keep driving with P0700 stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light means a fault was logged and the car should be checked soon; a flashing light means a severe misfire — slow down and get it seen as soon as possible, because severe misfire can quickly damage the catalytic converter. The safe read of this page is the mileage and the components, not permission.
Does a code mean the car is recalled?
No. Recalls are filed by campaign and matched by VIN, and none of them are triggered by a scan tool. If you want to know whether an open recall applies to one specific vehicle, check the VIN at nhtsa.gov/recalls — that is the only source that settles it.
Why do the counts here differ from other sites?
Because these are not estimates. Every number on this page is a count of documents in NHTSA's own files: manufacturer communications that name the code in their filed summary, and owner complaints that name it in the narrative. We do not model, weight or extrapolate them.
Will clearing the code fix it?
Clearing turns the light off and erases the freeze-frame data a technician would have used to work out what happened. If the condition is still there the code returns, usually within a few drive cycles, and the diagnosis now starts from less information than before.
