I spent about an hour above and below my car trying to find the source of an ATF leak (probably only several drops after shut down), right front, between radiator and wall of engine bay.
The diagram below matches what I've seen snooping around today...

The leak may be a pin hole, producing a fine pressurized mist that is lightly wetting the general area. I suspect hose 7 (soft part near radiator) in the diagram.
Hose 5 is damp (weeping). I'm sure others are or will be soon.
I'm familiar with the fire/safety concerns, so it's time to put the car up in the air for awhile and get to work. I want to replace all flexible lines in the trans cooling system. I'll appreciate some help with the following questions:

- How much of the exhaust must be removed?
- Anything I should ask to shop use in terms of hose type and construction?
- Is their a consensus on whether it's better to reuse the original hose crimps, or remove them and use appropriate clamps?
- Can anyone recommend a hydraulics shop in the northern Virginia area?

Generic 300 psi hose is what I used. I got the shop I had mine done at use the original style crimps. If they lasted for 25+ years; why change it?
You must drop the exhaust to get at those lines, not fun.
