I like my idea, granted you can get around it with a pair of bolt cutters, but if you get a cut resistant lock where thereisnt a big arm it would work a lot better.  I wanna weld a chain link to my tranny shifter, and a chain link to my t-case shifter.  Then I can put my tranny in say 2nd, 4th, or reverse, and then lock it up.  The crooks wouldnt be able to shift out or gear, and my truck doesnt like starting out in 2nd, and theirs no way in hell it would go anywhere locked in 4th.  And if you lock it in reverse and back into your spot  its gonna be fun to get out of that one.  Or you could just bolt a electric fence controller to the body, and set up a remote, and     their 


My dad used to leave his t-case in nuetral on his landcruiser back in the early 90s, and he actually had a guy break in, stole some of his tapes and stuff, got the truck hotwired, but then couldnt figure out how to get it to roll anywhere   the guy just didnt think about it.  My dad came out of work and found his landcruiser already warmed up for him (Feb in Colorado)

What if there was a way to remove the stick of a tranny?  i dunno how, but mabye a twist lock type of connection, so you put the stick in the hole, push down, and twist, and it locks into place, then it is ready to drive.  Then when you get somewhere, you park, put it in gear, push down, twist the stick, and it pops out.  Then the crook has no shifter, and you have a handy club to beat people with
