ALUMINUM THREAD REPAIR
Damaged or worn threads in the aluminum trans-
mission case and valve body can be repaired by the
use of Heli-Coils, or equivalent. This repair consists
of drilling out the worn-out damaged threads. Then
tap the hole with a special Heli-Coil tap, or equiva-
lent, and installing a Heli-Coil insert, or equivalent,
into the hole. This brings the hole back to its original
thread size.
Heli-Coil, or equivalent, tools and inserts are readily
available from most automotive parts suppliers.
