Dropping the pan every time for a transmission service is messy and the fluid is HOT.
So....during the last service I swapped back to my original pan, after I cut the tube to the correct ZLE length. A friend welded the bung in the aluminum pan, the pan was drilled and cleaned before I took it to him. Took 5 minutes.
The hex plug is barely lower than the aluminum crossbar behind the oil filter. But many other things, notably the exhaust, are lower. I'm not concerned.
I don't change the filter every time, so this makes a fluid change easier. Even when the filter is changed, the fluid can be drained before the pan is dropped........much less chance for a mess and getting burnt.
