    I don't know where you got that idea ....... After the original comment at the end of my post, nothing has
    been Bolded, nothing has been ALL CAPS and nothing has had a large font. I was simply asking!

    What I would like to see is this thread stay on the original subject. Since my last post about the planet gears
    and needle bearing, there have 19 post (oops, thats 20 posts now, another post while I am writing this one)
    that have nothing to do with building the 200-4R. If I'm looking for information on the 200-4R, this is NOT
    what I want to read. I suppose if I stop posting, then there will be very little extraneous additional posts. There
    will be no reason to tell me it will never last, no reason to tell me to use a different transmission, no reason to
    tell me it's expensive, no reason to .........

    You have the Recent purchssed NOS GM Planets.
    Could take apart and rob the needle bearings no longer made.

    yeah its unfortunately a fact that this hobby is a FINANCIAL, BOTTOMLESS pit ,
    for parts and tools required, and every time without fail, if you even begin to think
    that you have something working correctly , something either breaks ,
    on your car or expensive tools, or you see some vastly better,
    stronger or more tech advanced component advertised,
    or you find out you could do some job far faster ,
    and to much improved specs if you purchased some tools you don,t yet own.

    Dont need it.
    Why GM Had Highway gears.
    That overdrive costs $2000- 8000 more.
    All fail but Gear Vendors.
    Tremec.
    4L80E.

    I really like Budget Math.
    Lets say you make or earn $25 per hour.
    $2 k you have to work 80 hours.
    $8k you have to work 320 hours.
    Skip paying all your bills too.

    I do and I have both with OD.

    Huh ??? That's not realistic, cannot skip paying bills and I don't need a Gear Vendor OD. I already have OD, save $8k.

    if you look at the facts here,
    the 200r4 did not fail under stress, or during a race or hard launch, or towing a heavy load or on a long trip in country with lots of hills to climb, and the cars weight and lack of decent traction acts like a fail/safe or fuse,
    limiting any shock loads as the tires are much more likely to loose traction before the transmission start's puking its internals.
    due to not being able to handle the current engines power / torque .
    no, from all the evidence, that was previously posted,
    the transmission simply had failed because the shifter / gear selection controls were not properly adjusted prior to starting the engine,
    or the cooling lines and coolant level and type of transmission fluid was not functioning correctly.
    this is far more common that you might think, and as a result I suggest a good amount of time spent in researching proper cooling accessories, like trans fluid coolers and linkage adjustment be done prior to starting any new engine & trans install.
    Ricks doing an exemplary job in refurbishing the 200r4 transmission, and its cooling lines and shifter linkages etc.

    and if its properly re-installed and adjusted prior... to that engine being restarted,
    I doubt Ricks going to have issues, and now that hes found a source for even more replacement parts and has gained considerable experience rebuilding ,
    that 200r4 I would be rather foolish to not give the new re-built transmission a second chance at providing the car with a long happy life.
    now just as obviously, if the engine does prove to overwhelm the transmissions ability to provide the car with dependable power transfer characteristics,
    looking into how and why components should be upgraded would be a sensible route to look into further.
    personally I don,t think Rick's likely to have continuing issues simply because the same basic 200r4 transmission ,
    has been used behind the turbo v6 engines an significantly heavier cars with similar horse power.
    the 200r4 is a well proven transmission, with an over drive top gear ratio, which is similar the the more common 700r4 used in corvettes, but its more easily swapped with the th350 than the 700r4 .
    obviously time and experience and some research into upgrades if it becomes an issue later won,t hurt either.

    He is lacking 1 part.
    The special Valvebody BRF GN Turbo 6.
    Or John found the TCI constant line pressure 200R4 Valvebody.

    What size rear tire, brand and model you running out back Rick out of curiosity?

    It doesn't matter, if they were 2 inches wide on the rear, the trans would not be good enough for some people.

    I had a much longer response, but I deleted it.

    Grumpy added.
    Only 1 trans fits right in place of 200R4.
    The 399 + 1 Turbo Beast.

    The more astute of you will notice he brought up that F’N 400 AGAIN!

    If you look at Grumpys own introduction on his website back when he started it alone its Obvious he started off as a Drag Racer.
    Dabbled in Road Racing some too.

    He knows what works and holds up too.

    Perhaps it is time to move on and add to the value of this thread about a “TBucket 200-4R project” and follow Indy’s stunningly detailed build and now rebuild of a 200-4R. Let’s focus on that and not lose the wealth of information Indy is generating specifically on the 200-4R. It’s not the most common trans. Finding and archiving this is pure fried gold.
