Product Description
46RE 46RH 47RE 48RE TCC Apply Limit Valve Kit
Sonnax Part Number: 22771A-44K
NO TOOLING REQUIRED
When the torque converter clutch (TCC) is fully engaged in listed Chrysler units, line pressure from the pressure regulator valve is directed straight to the TCC apply circuit, through the TCC switch valve, applying full line pressure to the TC clutch.
In worn or performance-enhanced transmissions, pressure can reach 150 psi or higher, potentially deforming or ballooning the torque converter. This deformation can negatively impact drivability, efficiency and overall performance.
Sonnax TCC apply limit valve kit 22771A-44K limits the amount of pressure applied to the torque converter to 130 psi without affecting the line pressure or creating drivability issues.
- Improved valve replaces OE TCC switch valve
- Protects the torque converter from ballooning and failure due to excess pressure
- Carburized steel valve combats premature wear
- Limits TCC apply pressure to a max near 130 psi depending on the set point of max line pressure
- Drop-in Zip Valve™ parts install quickly and easily
PACKAGE CONTAINS
- Valve
- End Plug
SYMPTOMS
- Damaged converter
- Converter concerns
- Internal converter damage
CAUSE
Chrysler 46-47RH/RE and 48RE transmissions lack a specific valve controlling apply side converter pressure. Excess converter pressure can cause converter damage, ballooning and converter failure.
CORRECTION
Sonnax drop-in TCC apply limit valve kit reduces converter clutch apply pressures to a level that is safe for converter components.
