    Group Buy Feeler: T56 Stage 2 Rebuild Kit

    All,

    After 8-10 months of waiting for Tremec to do another manufacturing run of first generation CTS-V T56 parts, I'm now seeing availability. As you may already know, the Tremec T56 transmissions in our CTS-Vs are unique, making some of the most important parts (e.g. gears, synchronizers, rings, and main shafts) incompatible with most other T56s out there.

    On Monday, I plan on calling my contacts at various shops to price out a group buy on a Stage 2 rebuild (normally $950). If you're tentatively interested, let me know. Personally, I'd rather get this done at the same time I install my McLeod RXT, but I'm willing to hold off for a month or two if it means a better discount for all. That said, once these parts are gone, it probably won't be until next year until Tremec does another run.

    Basically, regardless of whether you drive a stock-engined CTS-V, or you plan on taking your CTS-V above 600 RWTQ (an action that *will* grenade the stock transmission if you shift at those power levels) you can benefit from this kit. The primary advantages are:

    1. Higher RPM shifting
    The newer, hardened 1-2 and 3-4 synchronizers and springs allow for shifting at 7400-7800 RPM, versus the standard T56 limit of 5500-6400 RPM (depending on clutch inertia).

    2. No More Grinding
    If your transmission is grinding or "crunching" during shifting, your synchronizers are on their way out. You can bleed your clutch all you like, but it's only going to get harder and harder to shift until the entire transmission fails.

    3. Stronger Transmission
    Unfortunately, we cannot upgrade the mainshaft on the CTS-V transmission to a 31-spline version, but we can upgrade the aluminum shift forks and nylon pads to steel and bronze, respectively, to prevent them from breaking and grenading the transmission during hard shifts.

    If you want to do that, you might as well buy a new Magnum transmission for roughly $3,000. This is for people that are willing to pull the transmission and work on it for a couple of days.

    I'd be interested... it would have to be price-competitive with just sending the trans to Tick Perf

    You're saying it wouldn't be cost effective to let someone else do it? I've never messed with a tranny but I heard they're pretty complicated and I don't want to eff it up.

    Then don't mess with it. Some places offer a mail order service. It'll take a couple of weeks to get it back and you'll pay through the nose, but that sounds like it's more your speed.

    You are not alone. I've rebuilt a lot of manual transmissions for both cars and motorcycles and I would not touch a T-56. Additionally, many GM dealers will go with replacement or remanufactured T-56s because the success rate on their own in-house rebuilds is not that good and correcting a mistake is expensive.

    Considering the fact that four dealership techs with a GM Tech 2 wasted three hours of my time and $60 worth of fluid trying to bleed my brakes... yeah, I can see why they'd have a hard time with a transmission rebuild.

    $60 on brake fluid? What kind of magical stuff was that?

    They went through three bottles of this. And they dripped it all over my engine bay and new Forgestar F14 wheels.

    Where's "Cadillac Customer Svc" now?

    I really like the idea of tougher synchros for 1-2 and 3-4 gears. Also, I've done a couple of Muncie four-spds back in the day, but that was, as I say, "back in the day." I'm at the stage of my life where I would prefer to drop the car off in the morning somewhere and pick it up at the end of the day after I write a check.

    Sure would like to see how this goes, Fuzzy.

    the kit is all that? (in the picture?)

    if so, definitely yes I'm interested. I have a grinding problem with third.

    the only other options I've come up with are complete camaros... one sold in san diego with an auto trans swap and a barely used T56 that came out of it.. it was a beaut. sold for $1500.

    but yeah, this is something that has been on my mind, even if the group buy isn't a deep discount, I'm interested yes, definitely.

    how do i... subscribe to this thread... found it.
