I suppose the copper piece matches the original diameter of the whole and you drilled it to match size?

It's been almost 7 years ago. But, I do believe the vent hole is quite small. However, I feel certain that the copper pipe ID is equal to or larger than the OE hole. Also, the mod was made when I rebuilt the tranny (it was disassembled).

I will be drilling and tapping both my diff and trans vent holes so I can run some line up higher to keep water out when I plunk it in a river.

I will then clean the whole thing and plan on painting it this color.

I specifically requested my transmission NOT be painted because it will dissipate heat better. But then I live in the dry southwest. For someone who may be driving through salt and pumice covered winter roads I can see the wisdom of paint as a corrosion inhibitor. The worst thing is when your transmission runs hot in humid weather while covered in salty road sand, then it REALLY corrodes fast.

my transaxle is on the bench right now as i do Speedi-Sleeves on the output flanges. vent hole is very small... about 3/32"

primed my trans with Aluminum primer then painted with gray Rustoleum during the rebuild. salt is our enemy in the far north, not heat.
