How can I do a crank re-learn on a 99 f body with a 402 in it with a turbo 400tranny. The car was a 6 speed car and now someone else flashed it with an auto pcm. The problem is it is missing half the stuff it needs to do the re-learn. There is no vss, no parking brake, no computer at all for a auto so when I try the relearn it just fails because of everything missing.
