Leakey transmission

[GuidoInc]

I have a 96 Q45 with 90,000 miles and has a severe transmission leak. I notice the fluic dripping from the 4 electrical plugs beneath the rear extension. I would assume the leak is the rear extension seal since it's so close (and hope it is because it is relatively easy to fis). If the turbine sensor is leaking where does it come out? Is there a way I can determine the source. The parts guy said the rear seals rarely go out. What is more likely to leak turbine sensor or rear extension seal?

Thanks all

Turbine sensor, the ATF turns acidic [from not changing it] and eats thru the seal and travels inside the wiring harness to the plug where it leaks out.

Not to say that front and rear seals don't fail also from the same cause.
