I had to change mine to, the hardest part was getting the connector pluged in again. I used a short(5" long) adjustable wrench, and I unplugged it from above. You can see it if you look from the drivers side, looking down on the tranni, looking between the firewall and the exhaust manifold. I could just reach my arm in there to unplug it with one hand, then I used the wrench from below, drivers side. Try to clean off any grease before you take it out so you don't get dirt falling in the hole.
