Dealer cost

$800-4000

Likely causes

  1. 1

    Low transmission fluid level— Most likely

    Check the fluid level cold and hot — some machines read differently. Use only CIH Hy-Tran Ultraction fluid or equivalent.

  2. 2

    Worn pressure regulator valve— Possible

    The regulator valve and its bore wear over time. Debris in the fluid accelerates wear. This is a workshop job — requires dropping the transmission sump.

  3. 3

    Plugged transmission filter— Possible

    A blocked internal filter starves the pressure regulator of flow. Change the transmission filter if overdue.
