NewYall automatic transmission solenoid kit for Honda & Acura — gasket and O-rings, direct-fit replacement

NewYall's automatic transmission solenoid kit includes a replacement solenoid plus gasket and O-ring seals designed to restore hydraulic control in compatible Honda and Acura automatic transmissions.

This kit provides a direct-fit solenoid assembly with accompanying gasket and O-rings for a range of Honda and Acura models from the early 2000s through 2011. It's crafted to match factory mounting points and sealing surfaces so you can replace a worn or leaking solenoid without modifying the valve body. Use this when troubleshooting delayed shifts, transmission fluid leaks around the valve body area, or when performing preventive maintenance on compatible AT transmissions.

Which vehicles will this NewYall solenoid kit fit?

The kit is specified for multiple Honda and Acura models across several years and engine variants. Confirm your vehicle's model year and transmission type before purchasing to ensure compatibility.

• Honda Accord 2.4L VTEC AT (2003–2007)
• Honda Civic 1.8L i-VTEC AT and Civic CNG (2006–2011)
• Honda CR-V 2.4L models (2002–2006 VTEC and 2007–2011 i-VTEC)
• Honda Element 2.4L VTEC AT (2003–2008) and Honda Fit 1.5L VTEC AT (2007–2008)
• Acura TSX KA 5AT (2004–2008) and Acura RSX KA 5AT (2002–2006)

How does this solenoid kit improve transmission performance?

Replacing a degraded solenoid and failed seals can restore correct hydraulic pressure control inside the valve body, which helps the transmission shift smoothly and reliably. While not a fix for mechanical gearbox damage, it addresses common electronic/hydraulic causes of erratic shifting.

• New solenoid body to replace worn or intermittently functioning units
• Gasket and O-rings to prevent fluid leaks at the valve body flange
• Designed to match OEM mounting geometry for straightforward installation

What should I know about installation and compatibility checks?

Installation typically requires removing the transmission oil pan and valve body access—this is medium-difficulty work best done on a lift or jack stands. Always compare part shape, connector pins, and bolt pattern to the old solenoid before installation, and follow proper torque and fluid-fill procedures after reassembly.

• Inspect electrical connector pins and harness for corrosion before fitting
• Replace transmission fluid and filter if pan removal is required
• Torque bolts to manufacturer specs and test drive to verify shifting behavior

Will this kit stop all transmission issues?

This solenoid kit addresses electronic and sealing failures but does not repair internal mechanical wear, clutch packs, or planetary gear damage. Use it when diagnostics point to solenoid faults, pressure loss, or valve body leaks; for complex failures, consult a transmission specialist.

• Effective for correcting solenoid-related hydraulic control and leaks
• Not a remedy for internal gear, bearing, or severe valve body wear
• Recommended after confirming fault codes or pressure test results

Who is this for: The NewYall solenoid with gasket and O-ring seals suits DIY mechanics, independent shops, and fleet technicians working on compatible Honda and Acura AT models who need a direct-fit replacement part. Choose this kit if diagnostics indicate a failing shift solenoid, you observe transmission fluid leakage at the valve body, or you want to replace seals while servicing the transmission pan and filter.
