P2704 Transmission Friction Element "E" Apply Time Range/Performance
P2704 is a generic OBD2 powertrain code. It means “Transmission Friction Element "E" Apply Time Range/Performance” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.

What the wording tells you
“Range/performance” means the signal is electrically valid but doesn’t make sense against what the module expects from the other sensors. That points to a sensor that is dirty, slow or out of calibration — or to a real mechanical problem it is faithfully reporting — more than to the wiring.
“E”: where a car has several identical components, SAE tells them apart with letters. Which physical part is “E” is defined by the manufacturer — check the service information for your car before replacing it.
Can I keep driving with P2704?
The rule of thumb for this area (transmission): Drive gently and get it diagnosed soon. If the transmission is in limp mode, slipping or shifting harshly, keep driving to a minimum — carrying on can turn a sensor fault into a rebuild.
How P2704 breaks down
Powertrain. Engine, transmission, fuel and emissions — the codes behind the check engine lamp.
Generic code: defined by SAE, the same on every make.
Transmission.
The specific fault within this range.
Where to look: Transmission
Automatic, dual-clutch and automated manual transmissions: shift and pressure-control solenoids, speed sensors, gear-ratio monitoring, the torque converter clutch, fluid temperature and pressure, range sensors and transfer cases.
Typical causes in this area
- Low, old or wrong transmission fluid
- Failed solenoids or speed sensors
- Wiring and connectors at the transmission
- Internal wear — clutches, bands, the torque converter

Brimly reads stored, pending and permanent codes through a Bluetooth LE or Wi-Fi OBD2 adapter, explains each one offline from the same 2,693-code dictionary as this page, and clears them once the fault is fixed — each clear goes into the car’s service history with the codes it removed. OBD diagnostics are part of Brimly Forever, a one-time purchase; the PRO assistant explains a code for your exact car.

Frequently asked
What does P2704 mean?
P2704 is a generic OBD2 powertrain code. It means “Transmission Friction Element "E" Apply Time Range/Performance” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.
Can I drive with P2704?

What causes P2704?
“Range/performance” means the signal is electrically valid but doesn’t make sense against what the module expects from the other sensors. That points to a sensor that is dirty, slow or out of calibration — or to a real mechanical problem it is faithfully reporting — more than to the wiring. Typical causes in this area: Low, old or wrong transmission fluid; Failed solenoids or speed sensors; Wiring and connectors at the transmission; Internal wear — clutches, bands, the torque converter.
How do I clear P2704?
Fix the cause first, then clear it with any OBD2 scanner or app. Once the fault is gone the car also clears it on its own: the check engine lamp goes off after the self-test passes on three drive cycles in a row, and the stored code ages out after about 40 warm-ups. Clearing without a repair only hides it for a while — and resets the readiness monitors an emissions inspection looks at.
Is P2704 the same on every car?
Yes. P2704 is a generic SAE J2012 code, so its definition is identical on every make and model. What differs is the cause behind it and the repair procedure, which depend on the engine — that’s why the assistant on this page asks for your car.
