Sonnax 84754-44 Oversized Torque Signal Valve for GM 4T65-E Transmission

The Sonnax 84754-44 oversized torque signal valve is designed to address pressure control problems in GM 4T65-E transmissions, particularly when experiencing P1811 codes or slip/shudder conditions caused by worn or sticking torque signal regulator valves.

Key Features:

• Restores proper hydraulic clearances and function of the torque signal oil circuit
• Salvages valve bodies with worn torque signal bore and/or sticking valve
• Corrects P1811 code, slip/shudder condition and intermittent no/poor line rise
• Oversized design compensates for bore wear
• Fits 1997-UP GM 4T65-E transmissions

A worn or sticking torque signal regulator valve and bore reduces or prevents line rise, resulting in long soft shifts and slippage. Reconditioning the bore and installing this oversized valve restores proper hydraulic clearances and circuit function. This valve requires reaming tool ST84000-TL44 or 84741LA for proper installation.

Installation Note: The PCM must be reset/relearned after any valve body repairs, as aftermarket scanner relearn procedure or battery disconnect for 12 hours may not restore drivability and line pressure control.
