Description

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

Symptoms:

  • High line pressure
  • Low base line pressure
Cause:
Worn, tired OE pressure regulator springs or aftermarket springs with higher spring ratings.
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.
