Showing the 25 model years where P0730 appears most; it is on file for 43 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.

P0730 by make
The same record, one make at a time: the model years, bulletins and owner reports that name P0730 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 vehicle was towed to the dealer, where DTC P0730 was retrieved, indicating an Incorrect Gear Ratio, and the dealer determined that the transmission needed to be replaced
The dealership scan tool later pulled diagnostic code P0730 (Incorrect Gear Ratio) along with multiple clutch performance failures (P07A4, P07A2, P07A8)
The service department scanned the onboard computer (from the parking lot, NO actual physical inspection done) and pulled internal transmission fault codes P0730 (Incorrect Gear Ratio) and P0746 (Pressure Control Solenoid "A"…
Codes: P0777 - pressure control solenoid b - stuck on, P0741 - torque converter clutch solenoid - stuck off, P0730 incorrect great ratio
44 manufacturer filings name P0730. 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 P0730 means
Source: SAE J2012 / OBD-IIThe gear ratio the transmission achieved is not the one it selected.
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 P0730
Source: NHTSA files and the OBD-II standardCan I keep driving with P0730 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.
