My search so far shows tapping the Front Clutch orifice, then drilling out a plug starting around the .140” range. So I have a few blank plugs, a 1/8”-27 tap, and a few drills (.136”, .1405”, .1406”, and a .144”) for testing.

But before I start, I want to confirm that this is the direction I need to go.

Review: The “clunk” noise on the low speed 2-3 shift (driving around town) is the only issue. Medium to hard accel it shifts good.

Thank you guys!
