Hey Eric, thanks for the response. Just to establish a baseline ... presume I'm a complete and total idiot. Why? I'm looking at it thinking "that is the most accessible oil pan I've ever seen..." Why? Because it is the TRANS Pan! You just CAN'T get good clients anymore.

 

The two lines that go into the top of the trans on the passengers side, in and out to the radiator? The top line appears to be the one that is leaking oil. It looks like motor oil, smells and tastes like motor oil. Why would a line at the trans be leaking motor oil?

 

Can I fix it, or is it indicative of a real problem?

 

Idiot Joe.

Hi,

 

Ok, trans line would not be leaking engine oil, and correct, they go to trans cooler in the radiator. Will be a little difficult, but you need to trace the lines going forward and find the source of the oil leak that is getting on the lines and running back towards transmission. you may have a valve cover gasket leaking oil onto trans lines

O.K., back of the engine, under distributor is a black "sensor" (switch/unit what do I know) about 2 1/2" long and about 3/4" wide, with a silver hexagonal base, obviously, for the wrench. Leaking like a sieve.

 

Oil pressure sensor?

Oil pressure sending unit?

Uhmmmm...?

 

Since I'm probably going to have to ask for it by name when I get a new one, gotta name for me ? Let me re-frase that ... gotta probable name for this part?

Hi,

 

That is the oil pressure sensor, and is known for leaking. make sure they give you a new o-ring with it. Believe they run around $20 for the sensor
