Product Details

The Sonnax 154740-09K is a drop-in shuttle valve kit designed to restore proper line pressure control and prevent future wear in GM 8L45 and 8L90 transmissions. This Zip Valve™ kit addresses common transmission issues caused by worn OE shuttle valve sleeves that result from continuous shuttle valve oscillation.

Key Features:

  • Shuttle sleeve manufactured from highly wear-resistant billet aluminum to prevent wear
  • Hardcoat anodized aluminum valve combats premature wear
  • Critical valve spool made 30% longer than OE for improved sealing and durability
  • Upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control
  • Drop-in Zip Valve™ design for quick and easy installation

Addresses These Problems:

  • High line pressure resulting in harsh shifts
  • Loss of cooler and lube flow
  • Overheating of the transmission and converter
  • Improper positioning of the pressure regulator valve due to balance line pressure exhaust

This kit provides a reliable, long-lasting solution to restore hydraulic integrity in your GM 8L45 or 8L90 transmission valve body. The enhanced design utilizes superior materials and extended valve dimensions to operate in unworn bore sections, ensuring optimal performance and longevity.

Product is at the harbor haven't seen it yet.

Great pricing and availability offered.

Great service. Great product and great price.

So I was skeptical due to a lot of negative reviews online, but I seen they had a great price for Toyo extensa II tires about half the price of everywhere else. So I bought all 4 with the free shipping option, and they were shipped to me in 3-4 days each tire had a different tracking number but they all showed up at the same time. So I will definitely use the site again.

Easy and fast, found what i needed and was able to order it.

So far - So good. Waiting fot delivery

Thank you
