Case Porosity Repair
Some external leaks are caused by case porosity in non-
pressurized areas. You can usually repair these leaks
with the transmission in the vehicle.
1. Thoroughly clean the area to be repaired with a
cleaning solvent. Air dry the area.
WARNING
!
Epoxy adhesive may cause skin irritations
and eye damage. Read and follow all
information on the container label as
provided by the manufacturer.
2. Using instructions from the manufacturer, mix a
sufficient amount of an epoxy to make the repair.
3. While the transmission case is still hot, apply the
epoxy. You can use a clean, dry soldering acid brush
to clean the area and also to apply the epoxy
cement. Make certain that the area to be repaired is
fully covered.
4. Allow the epoxy cement to cure for 3 hours before
starting the engine.
5. Repeat the fluid leak diagnosis procedures.
Transmission Fluid Cooler Flushing and
Flow Test
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:
