Trans cooler questions

[Scott]

Just drill and tap the pan. No welding in bung required. I drilled and tapped at the bottom front of the pan, 1/2c inch from the bottom of the pan from the position where the fluid would rest. It takes guts to drill and tap a $200 pan, but it is aluminum and simple.

Sounds like a plan, easier to drill and tap than have a bug welded. I believe the sender is a 1/8" NPT, but will find out once the gauge arrives. Thanks!
