Oil Cooler Flushing & Flow Check: Notes

NOTE: Use the Transmission Oil Cooling System Flush and Flow Test Tool (J 45096) or equivalent to flush and flow test the transmission oil cooler and the oil cooler pipes after the transaxle is removed for repairs.

GM studies indicate that plugged or restricted transmission oil coolers and pipes cause insufficient transmission lubrication and elevated operating temperatures which can lead to premature transmission failure. Many repeat repair cases could have been prevented by following published procedures for transmission oil cooler flushing and flow checking. This procedure includes flow checking and flushing the auxiliary transmission oil cooler, if equipped.

Only approved automatic transmission fluid should be used when doing a repair on a this transmission. See RECOMMENDED FLUID .

The service procedure steps for oil cooler flushing and flow testing are as follows:

  1. Machine set-up.
  2. Determine minimum flow rate.
  3. Back flush.
  4. Forward flush.
  5. Flow test.
  6. Code recording procedure.
  7. Clean-up.
