Speed Sensor coming lose ..

My speed sensor (cable) came lose so my speedo wasnt working. Since it came lose it was spitting trans oil. I thought the cable just attaches to the tranny. I could be wrong.

The speed sensor attaches to the transfer case, not the transmission. So if there is a leak from where the speed sensor attaches, it's leaking ATF from the transfer case. If tightening the bolt that holds it in place doesn't fix the leak, odds are that the rubber o-ring that keeps the ATF from leaking out via where the speedometer sensor housing bolts to the transfer case is nicked or cut.

The shop is replacing the speed sensor cable because the bolt is dented. With that said if the bolt isn't in then it can leak fluid from the transfer case? I was afraid that the transfer case was cracked but the tech said it isn't. What could be the cause of this from happening?

They're replacing the cable because the bolt is dented? If the bolt isn't in, the speedo assembly won't stay in place, let alone cause a leak simply because the bolt is missing. Again, without seeing it, my guess is the leak is caused by nothing more exotic than the speed sensor housing simply wasn't installed all the way in due to the loose bolt, at least from how you explained it before. Coupled possibly with a possibly cut/nicked o-ring like was mentioned above.

I found pics hopefully this will clarify all the confusion. The shop is replacing the cable w/ the speed sensor.

The cable shown ... the attached piece was loose. So this made fluid leak out?? The jeep is stock aside from the lift and exhaust. Also, there is a plate covering underneath so Im puzzled as to how it came loose.
