Product Details

The Sonnax 76990K is a drop-in pressure regulator boost valve and sleeve kit designed to restore proper hydraulic function in Ford AOD automatic transmissions. This OEM-ratio replacement kit addresses common transmission problems caused by worn boost sleeves, including poor line rise, direct clutch failures, and soft shift complaints.

Key Features:

  • Highly wear-resistant aluminum sleeve prevents premature wear and oil leakage
  • O-ring seals on sleeve outer diameter provide positive seal against the valve body bore
  • Hardened steel boost valve with tight tolerances for minimal clearance and maximum efficiency
  • Drop-in Zip Valve™ design installs quickly without special tools
  • Restores hydraulic integrity to the pressure regulator assembly

This kit solves a common problem in AOD transmissions where the hardened steel boost valve continuously reciprocates within the aluminum sleeve, wearing the inside diameter and allowing excessive oil leakage. The Sonnax 76990K features a specially manufactured aluminum sleeve with integrated O-rings that eliminate feed oil escape, restoring normal line pressure operation and preventing transmission damage.

Kit Includes: Boost valve and O-ringed sleeve

The refrigerator was at my home in 3 days!!! Was 300 dollars cheaper than even Amazon and just a quick getting it. Far exceeded my expectations and will absolutely order from them again. It was bought to replace a furrion 10cu ft fridge that gave out after a year and 4 months, very disappointing. The fit was right on the sides but did not have to trim anything to fit it in and the layout of the inside is much better than the furrion. I ordered the mounting brackets and sour patch thru a different company and still have not received them.

Ok

Rims shipped in a timely fashion and arrived when they said they would

All good
