For future readers of this post, when you change the CPS: 1) do it on a cold engine /transmission/ exhaust pipe unless you like roasted right forearm. 2) There is a small plate bolted to the transmission that holds two electrical plugs in place, one is the CPS plug. Remove this plate by its 13mm bolt to get easier access and visibility of the CPS, then re-bolt it into place at the end of the process. 3) Wrap 1" wide blue masking tape around the top of the 11mm socket, leaving 1/4 inch of tape sticking out above the top of the socket. Put the bolt in the socket and tape down the bolt head. This will hold the bolt in the socket until you get it started and will keep you from dropping it into the bell housing hole. 4) For the CPS bolts I used the 11mm socket, 3"extension, universal adapter, then two long extensions and ratchet to have enough length to access the two CPS bolts. 5) Don't connect the electrical plugs until after the new CPS is secured in place, but rather put the wire/plug on the forward side of the bell housing to help keep the new CPS in place as you are getting the bolts back in. Replacing this part is, as the Brits say, "fiddly". If you get frustrated, like any other difficult job on the XJ, walk away from it for a while.
