(4 Grand Cherokee replace the crankshaft position sensor?

I have a 1994 Jeep Grand Cherokee with a 5.2 liter V8. My problem is we just replaced the Automatic transmission and now have No Spark. I suspect that the wires from the position sensor are pinched between the transmission and the block or that the positioner my even be broken loose from the engine. I think from the other post that I now know where it is. My question is this: How do I change it? Can anyone give me some guidance to change it out?

Thanks in advance for your help

Here is a site that may help you out. It's right above the starter on passenger side next to firewall. check the wires they may have been cut or torn apart. Dale jeepman600@sbcglobal.net
