    Just wondering if there are different versions or years/models of this transmission and what makes one year or model better or worse than the others. Mine is out of a 88 caprice wagon. I have the tag number. anybody got any info on build changes or upgrades from the general throughout the years?
    THanks!

    Yes there is different versions. For example the GN 86-87 used a brf valve body some have the Kc valve body some have BQ and so on and so forth. The case is essentialy the same but the internals differ valve bodies govenors etc. The brf is suppost to be the most desired but i not 100% on that.

    Im thinking this one is a KCF code trans. Im hoping that it has a bit more strength since it was in a Caprice wagon.
    Thanks!

    checked it again....its a KTF code.
    I found this article on Hemmings web page.
    http://www.hemmings.com/mus/stories/200 ... ture9.html

    and also this info.....

    Here is a chart of some of the more popular codes:
    TH-200-R4 ID's:
    ID Year(s) Application
    KZF Olds 442/Hurst
    CZF 85-88 Monte SS
    CRF 85-88 LG4 305 powered Monte Carlos/Pont Gr Prix
    BRF 86-87 GN/T-Type/Turbo Regals
    BQ 84-85 GN/T-Type/Turbo Regals
    BR 83 Model T-Types

    OZ Hurst Olds
    OM Olds 350 Diesels
    OG lds 307
    BY V-6 252 Cars
    AA and AP Cadillac's

    Unfortuately, I dont see a KTF code here, so I dont know whether its a better one or not... :roll:

    Bill,
    The 200-4R unit that I have is a CTF code. Apparently from an '89 Chevy Caprice. It will definitely need some upgrades for a performance application. Valve body, governor, servo, etc.
