F20b swap + F23a Tranny = ???

Sad, but true. They hey day of 6th gens has come and gone. I'm on my 3rd 6th gen and i've had it since 2013, its had maybe 4 or 5 engines from all my prior exploits. I used to live in japan and its common for auto trans to be on their cars. Even still when my 99 at went out i welcomed the opportunity to install an m2b4 trans. go with what's tried and true.
