so I noticed a wet spot under the truck about 2-3 weeks ago. She had not been driven in about 2 months. I just got a chance to look under her and there is a leak rom the rear of the tranny on the nose cone. Picture attach, can someone please help me identify what this is?

 

That's your speedometer sensor. I believe it's called the output speed sensor

 

Just replace the o ring.

 

Vehicle speed sensor. Output speed sensor is further forward.

 

Thanks guys for the assistance. I was really worried that it may have been from the pan because I did so much work up there, I am relieved to see it's just this. O-ring and done.....

 

anyone got an idea where I can pickup the seal "o-ring". Cant seem to locate one anywhere. any help appreciated.

 

Dealership? They can't charge too outrageous a price for it...... Either that, or the parts store, see if they can match one up for you.

 

Could just buy the the sensor and use that o ring

 

found it from a tranny store in LA. PATC.....$3.95
