There are BINS with richly detailed XDF files that support that combo of engine and trans. Which PCM are you going to use? For the P01 PCM, I'm using the 8322 BIN but 2156 and 2088 are also very good. 2156, probably the best of the three.

For a P59 PCM, the 7603 BIN and XDF combo is your only real choice though 7604 has seen some recent improvements in XDF support.
