Transmission Fluid Cooler Flushing and Flow Test: Notes

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.

NOTE: Use the 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 or replacement. Use only GM Goodwrench DEXRON®VI automatic transmission fluid in the J 45096. The AF33-5 uses T-IV automatic transmission fluid. After completing the flushing and flow test procedure, remove the residual DEXRON®VI left in the oil cooler by carefully blowing out with compressed air. Time allowance for performing the cooler flow checking and flushing procedure is included in the appropriate labor time guide operations. The service procedure steps for oil cooler flushing and flow testing are as follows:
