What to do when ya realize somebody forgot to tighten a transmission line in a spot you can barely see, never less reach??
Noticed a drip in the bilge under STBD trans and thought I'd better check while can still get to it. Fired up the engine, ran through all the gears, and sure enough the fitting dead center front of the pan is the source. It's a low pressure return line, with no way to reach it besides pulling the transmission pan.
So before spending two hours standing on my head, I hit up a buddy for a tool I haven't used since GM stopped running distributors. A crowfoot. And lucky for me, he had a metric line wrench set..
Add 24" of wobble extensions, and the 18mm was just loose enough to easily slide over the 11/16 hydraulic hose end, but not slip. Got a good half turn on it, problem resolved under 3 minutes.. Probably be another 20 years before I need one again...
