Product Description
C6 Elevated Pressure Main Pressure Regulator Spring
Pack of 20 Springs
CALIBRATED TO OE GAS LINE PRESSURE - FITS DIESEL AND GAS
Sonnax Part Number: 36946-01K
The OE springs in many Ford transmissions wear or become fatigued, causing low baseline pressure. OE replacements are hard to find, and many aftermarket springs have unacceptably high spring rates. The Sonnax elevated pressure main pressure regulator springs are intended to provide a minimal baseline pressure increase (approximately 10 psi over OE baseline pressure), enough of an increase to help restore full line pressure. The springs may be used to replace worn OE springs and also to correct low line pressure caused by worn transmissions.
- Highest quality spring material
- Designed to gently exceed OE spring rates
- Manufactured to tight tolerances
- Drop-in installation requires no modification
- Saves time looking through cores for replacement springs
PACKAGE CONTAINS
- Springs (20)
SYMPTOMS
- Soft shifts
- Poor shift quality
- Low base line pressure
- High line pressure
CAUSE
CORRECTION
The Sonnax elevated pressure main pressure regulator springs are designed to provide an effective baseline pressure. The slight increase in spring pressure compensates for wear elsewhere in the transmission.
