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 con-
sists of drilling out the worn-out damaged threads.
Then tap the hole with a special Heli-Coil™ tap, or
equivalent, 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 suppli-
ers.
