    This is the Powertrain Technical Reference Thread.

    A Technical Reference is a document, link or thread containing factual information such as diagrams, specifications, procedures, etc.

    This thread contains technical reference documents, links to threads useful as technical reference, as well as links to outside reference sources.

    Please do not post comments here. Instead PM me or post a new thread commenting on a particular post in this thread.

    Please do feel free to post your own technical references, but please insure that they are authoritative - I want to try to avoid mis-information in this thread!

    Thanks,

    Chris
