Product Details

The Sonnax 77741-02K is a precision-engineered transmission valve kit designed to restore proper hydraulic control and shift quality in automatic transmissions. Sonnax is a trusted name in the transmission rebuild industry, manufacturing high-tolerance replacement and upgrade components that meet or exceed OEM specifications.

This valve kit addresses common wear-related issues in the transmission valve body, including pressure loss, erratic shift behavior, and delayed engagement caused by worn or out-of-spec valves. Sonnax valves are manufactured to tighter tolerances than OEM parts, helping to extend service life and improve overall transmission performance.

Key Features:

  • Precision-machined valve components for tight bore fit and reduced leakage
  • Restores proper hydraulic pressure and shift timing
  • Manufactured to tighter tolerances than original equipment
  • Direct replacement for worn or damaged OEM valve components
  • Engineered and manufactured in the USA by Sonnax Industries

Ideal for professional transmission rebuilders and shops looking to deliver a reliable, long-lasting repair. Always refer to the Sonnax product instruction sheet for installation procedures and valve body bore sizing requirements.

It fits!!

Haven't found the time to work on my SL.

Everything came in really quick and packed well. Apparently I just ordered the wrong part.

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Friendly, Helpful, Great Price !! Shipping was Fast

So far so good. Let you know in 2 days.

Great prices and a surprisingly fast delivery, which despite choosing the most economic choice (2-14 days), I received the items in 5 days - saved more than half in shipping. Great all around experience and great product extremely well packaged. Thank you, folks!

Easy transaction, shipping was lightning fast!

Quick, and easy.
