A friend of mine swapped an auto LS into an auto del Sol. It is a pain in the ass. The tranny mount bracked on the frame has to be cut off and re-welded on. In a CRX, that is going to require the same or some kind of custom mount. Wiring is a pain in the ass because the LS auto tranny has it's own seperate computer to wire up. He got it all running great until he put a turbo on it. After going through three supposed "performance" tranny rebuilds, he swapped it out for a 5 speed. My advice to you, if you plan to boost or spray the motor, do the 5 speed conversion. If you are still interested in all the details of the auto swap, pm me and I'll get you in contact with my friend.
