P2758 on Toyota by model: symptoms, diagnosis and fix
The 2005-2012 Avalon with the U660E 6-speed automatic transmission develops a shudder or vibration during light acceleration, particularly in the 30-50 mph range at low engine RPMs. The shudder feels like driving over a textured road surface and is caused by the torque converter lockup clutch slipping. The issue is more pronounced when the transmission is warm and during gentle throttle application. Some owners describe it as a "rumble strip" feeling. The transmission fluid condition significantly affects the severity of the shudder.
Common Symptoms
- Vibration or shudder during light acceleration at 30-50 mph
- Rumble strip sensation during gentle driving
- Shudder disappears under heavy throttle
- Shudder more noticeable when transmission is warm
- Vibration felt through floorboard and seat
How to Fix
Start with a transmission fluid drain and refill using Toyota WS (World Standard) ATF only — do not use aftermarket ATF. A fluid change resolves or significantly improves the shudder in many cases ($150-$300). If the shudder persists after a fluid change, the torque converter may need replacement ($800-$1,500 for parts, $500-$1,000 labor). In severe cases, the entire transmission may need rebuild or replacement ($3,000-$5,000). Change transmission fluid every 30,000-40,000 miles to prevent the shudder from developing.

Owner tips & cautions
- TipA simple drain and refill with Toyota WS ATF fixes the shudder in about 60% of cases. Do 2-3 drain-and-refill cycles (drive 500 miles between each) to exchange most of the fluid. Much cheaper than a torque converter replacement.

What does P2758 mean on a Toyota?
P2758 stands for "Torque Converter Clutch Pressure Control Solenoid Control Circuit Stuck On." This code indicates the transmission control module detected that the torque converter clutch (TCC) pressure control solenoid appears stuck in the on/applied state. This solenoid manages the hydraulic pressure that locks and unlocks the torque converter clutch for efficiency. If it stays applied when it should release, the clutch will not disengage on demand, which can cause the engine to stall, shudder, or the transmission to overheat. This should be inspected promptly to avoid transmission damage. On Toyota it is documented across 1 model: Avalon.
What are the most common causes of P2758?
The most common causes of P2758 are: Stuck or faulty TCC pressure control solenoid, Low or contaminated transmission fluid, Valve body or hydraulic passage sticking, Wiring or connector faults, Debris blocking the solenoid, Faulty torque converter, TCM control fault.
