28250-P4R-315 Automatic Transmission Control Solenoid For Civic CR-V Integra 1.8

Description:

The 28250-P4R-315 Automatic Transmission Control Solenoid is used in automatic transmission hydraulic control systems to regulate fluid flow for precise gear shifting, clutch engagement, and pressure modulation. Commonly installed in Honda Civic, CR-V, and Integra 1.8L automatic transmissions where electronic control of hydraulic circuits is required for smooth shifting performance and drivetrain reliability. Automotive technicians, transmission rebuilders, and OEM service centers use this solenoid for transmission repair, shift quality restoration, diagnostic fault correction, and replacement of failed or sticking valve body solenoids in Honda automatic gearboxes.

Applications:

The 28250-P4R-315 transmission solenoid is commonly used in Honda automatic transmission systems including shift timing control, line pressure regulation, torque converter lock-up control, and hydraulic valve body operation in compact and mid-size passenger vehicles where electronically controlled hydraulic actuation is required to ensure smooth gear transitions, fuel efficiency, and proper transmission operation.
