Symptoms:

  • Jerking on coastdown
  • No lockup
  • Engine stall on engagement
  • Overheated fluid
  • Overheated transmission & converter

Cause:

Wear in the bore and sleeve cause hydraulic leakage. This may result in overheated fluid, engine stall on engagement, no lockup, jerking on coastdown and overheated transmission and converter.

Correction:

Restore proper hydraulic control by reaming the bore and replacing worn parts with Sonnax oversized torque converter lube regulator and plunger valve kit to restore proper clearances.

You need this if...

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
