    Hey guys,
    Im workin on a 2001 S-10 with a 12208322 OS.. This OS calls for 012700xx COS.
    Wanted to ask if COS5 was available?
    Reason i ask is we are fixin to up the shot to 125 on the V6 and id like to have him a Nitrous tune when he arms his kit.

    Thanks Guys,
    Jonathan

    Dont let me confuse you on this one...

    The truck is a 2001 S-10 4.3 Manual, He kept breaking the NV3500s. So they put in a 700R4 with Manual Valvebody.

    I searched on Holden Crazy for a 2002 S-10 4.3 Manual that has 12212156 OS cause i know that can use COS5.

    Does anybody else know where to look for a 12212156 OS with a Manual trans? Or shoud i just use the Automatic Tune, and turn all the codes off for the Trans?

    I don't know that turning off the auto trans codes would still stop the PCM from complaining about the 700R4... you might give it a try...

    or you might copy both transmission segments from a Corvette manual trans 12212156 file.

    COS5 comes as 02020005 and 01290005 only... there is no 01270005.

    But like you said your can swap to 12212156 and then you can use 02020005.
