42RLE

Symptoms:

• Shift concerns
• Low line pressure
• Burnt clutches
• Poor lube oil control

Cause:
Worn pressure regulator bore.

Correction:
This kit restores the pressure regulator circuit with an oversized pressure regulator valve, returning pressure regulation to like-new function.

Fits non-VLP units only

A worn OE pressure regulator valve in listed Chrysler applications can result in low line pressure, burnt clutches and poor lube control. Wear is commonly found at different areas in the pressure regulator bore. Wear at the spring end of the bore allows line pressure to exhaust resulting in low line pressure, soft shifts and burnt clutches. Wear at this area also will affect converter flow and the lube circuit.

The Sonnax oversized pressure regulator valve restores valve-to-bore clearances, allowing the pressure regulator valve to maintain correct pressure in all ranges. The aluminum valve is hard-coat anodized for wear resistance.

Note:
Does not fit units with variable line pressure (VLP). VLP units can be identified by the presence of the line pressure solenoid and transducer mounted on the valve body.
