Sonnax 154740-18 Pressure Relief Ball Valve Spring, 8L45/8L90
852-154740-18
Sonnax 154740-18 Features:
The GM 8L45 and 8L90 transmissions are having a recurring problem where the typical ball and spring seat is not opening and relieving pressure effectively. The OE spring design needs to see 400+ psi in order to open and relieve line pressure. As a result of this high pressure not being relieved, damage/cracks to the worm tracks can occur.
Sonnax pressure relief ball valve spring 154740-18 allows line pressure to exhaust between 300–325 psi which will prevent future cracking of the worm tracks and restore proper function of the blow-off ball and spring.
