Symptoms:

  • Low line pressure

Cause:

Line pressure control accumulator pistons are leaky, jammed or bound.

Correction:

This LPC accumulator piston is made of aluminum to match the expansion rate of the aluminum valve body (OE was steel). The piston restores SLT pressure and dampening. SLT is the boost pressure in this unit.
