Transmission Case Cleaning and Inspection

Callout

Component Name

Caution:

Do not use abrasive pads or bristle devices to clean the sealing surfaces. Abrasive pads produce a fine grit that can effect transmission function. Abrasive pads can also remove enough metal to create oil leaks.

Caution:

After cleaning the transmission components, allow to air dry. Do not use cloth or paper towels in order to dry any transmission components. Lint from the towels can cause component failure.

Caution:

Do not reuse cleaning solvents. Previously used solvents may deposit sediment which may damage the component.

Preliminary Procedures

  1. Thoroughly clean the transmission case assembly, including case threads, with clean solvent.
  2. Clean gasket sealing surfaces. Remove all residual gasket material.
  3. Inspect all threaded holes. If necessary, repair any thread damage.
