I have an A9P in mine. I had it due to the AOD at the time. I was taught the following....The A9L was for 5 speeds, and the A9P was for automatics. The A9L didn't like Automatics that much, but the A9P would go both ways.
Now, that's what I was taught. I am still using the A9P and have no issues at all, and I also have the TFS-1 cam, and ported P heads and a 5 speed. I say whichever you can find that fits your budget the best, snag it..
