What's strange is we know from other thread that 5.7L came with manual trans! But whenever I find a listing for manual trans it comes back to PCM that you did not include! 16156930

To further explain here is my post from that thread and theory...:
BJYN in Cal Data shows 5.7L Manual 16197427 (superceded to BPSA and differant PCM 16156930) so I thing the BCC Lookup spread sheet is same database as CalData.

On BCCFind it says Trans Type= all/no listing just like the other one gregs78cam posted and he swears it came from an auto truck. CalData shows it to came from PCM 16156930 but it is in 16197427. So maybe GM did not had learned by then how to have a bin for both? By seeing 2 of these now I'd bet the 16156930 PCM is missing a few pieces needed for auto trans?
