Vehicles with ZF8HP50, ZF8HP75 and Chrysler 850RE transmissions may exhibit insufficient line rise in drive ranges, soft shifts and/or burnt clutches. These problems may be caused by continuous oscillation of the reducing valve in the sleeve, creating excessive wear and a path for critical line pressure fluid to exhaust to sump. Reconditioning the bore and installing oversized pressure regulator valve kit 35740-40K restores proper hydraulic control and prevents wear by utilizing upgraded materials and minimal clearances. * Sleeve is manufactured from highly wear-resistant billet aluminum to prevent future wear* Hardcoat anodized aluminum valves combat premature wear* O-Ringed sleeve provides positive seal to prevent critical line pressure fluid from leaking to exhaust* Annular grooves help center the pressure regulator valve in the bore to reduce future side-load wear
