What Does P2704 Mean?
Friction element 'E' in the transmission is not applying within the specified time range monitored by the TCM. This performance issue indicates hydraulic pressure problems, mechanical wear in the clutch assembly, or a control solenoid fault.
Common Causes
35%
Insufficient or degraded transmission fluid reducing hydraulic efficiency
30%
Worn friction material or damaged seals on clutch pack E causing slip
20%
Faulty pressure control solenoid E failing to regulate apply pressure properly
10%
Blocked valve body passages or worn valve body components affecting fluid routing
5%
TCM calibration issue or electrical fault in control circuit
Diagnostic Steps
1
Step 1: Verify transmission fluid is at proper level and assess condition for contamination or burning
2
Step 2: Use scan tool to observe solenoid E command values and actual apply time during operation
3
Step 3: Conduct line pressure test to confirm hydraulic system is generating adequate pressure
4
Step 4: Test electrical circuit to solenoid E including resistance, continuity, and voltage supply
5
Step 5: Internal transmission inspection necessary if external diagnostics indicate normal operation
Estimated Repair Cost
$150 - $3,500
Parts + labor, varies by vehicle and location
Friction element 'E' in the transmission is not applying within the specified time range monitored by the TCM. This performance issue indicates hydraulic pressure problems, mechanical wear in the clutch assembly, or a control solenoid fault.
The most common cause of P2704 (Transmission Friction Element "E" Apply Time Range/Performance) is: Insufficient or degraded transmission fluid reducing hydraulic efficiency
Typical repair costs for P2704 range from $150 to $3,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience erratic shifting, gear slippage, or reduced acceleration capability. Driving with this condition can cause progressive transmission damage and unexpected loss of power.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2704 to identify the root cause.
