P2758 — Torque Converter Clutch Pressure Control Solenoid Control Circuit Stuck On

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm P2758 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
Subsystem check Command the torque converter clutch pressure control solenoid control circuit on and off with a scanner and watch the feedback signal; then remove and inspect the mechanism for sticking before replacing it.
Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2758 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2758 (parts and labor, USD, independent shop rates): Replace a shift solenoid: $300–$800; Transmission rebuild or replacement: $2,500–$5,500; Valve body repair or replacement: $700–$1,500; Transmission fluid service: $150–$350. Overall, fixing P2758 usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What does OBD2 code P2758 mean?

Torque Converter Clutch Pressure Control Solenoid Control Circuit Stuck On (P2758): a powertrain (engine/transmission) fault affecting the automatic transmission control. Short, gentle driving to a shop is usually possible. Most often caused by low or degraded transmission fluid, failed shift or pressure control solenoid, internal mechanical wear (clutches, torque converter).

How do I diagnose P2758 myself?

Start with a scan: confirm P2758, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the torque converter clutch pressure control solenoid control circuit, and verify the suspect component against live data before buying parts.

What is the most common cause of P2758?

The most common causes are: low or degraded transmission fluid, failed shift or pressure control solenoid, internal mechanical wear (clutches, torque converter).

Is it safe to drive with P2758?

Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

Will P2758 clear itself?

Sometimes P2758 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What does P2758 mean?

Behind P2758 is a specific failure in the automatic transmission control: torque converter clutch pressure control solenoid control circuit stuck on. The onboard computer stores it in the powertrain (engine/transmission) group after verifying the fault over repeated checks.

“Stuck” means the torque converter clutch pressure control solenoid control circuit is commanded to change state but feedback shows it does not move — or moves when it should not. Typical physical reasons are carbon or dirt jamming the mechanism, welded relay contacts, or a weak actuator.

To set P2758, the control module compares live readings of the automatic transmission control against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

Common symptoms of P2758

harsh or delayed shifting
transmission stuck in one gear (limp mode)
Check Engine or transmission warning light on
no movement in severe cases
shuddering at highway speed

What causes P2758?

welded relay contacts keeping the circuit permanently on
weak actuator motor or broken spring
mechanism of the torque converter clutch pressure control solenoid control circuit jammed by carbon, dirt or corrosion
low or degraded transmission fluid
failed shift or pressure control solenoid
valve body wear
wiring or connector faults in the valve body harness
faulty transmission speed sensor

How to fix P2758

Start with the cheapest and most common causes before replacing expensive parts:

Replace a shift solenoid — $300–$800
Transmission rebuild or replacement — $2,500–$5,500
Valve body repair or replacement — $700–$1,500
Transmission fluid service — $150–$350
