    Jim,

    You have these upgrades. Can you elaborate on the differences after installing them?


    Thanks

    The torque converter offered by Weistec is very impressive:

    http://www.weistec.com/7229tc.html

    They claim an average 0.2 second improvement in 60' times. That's going to translate into some greatly improved 1320' times!

    Keith, I honestly assumed you already had this...you can say hello to the 9s, probably some 9.80s would be my guess based on your times from Thursday.

    Mercedes 722.9 (7G) automatic transmission upgrades available from Weistec Engineering - Valve body, TCU, Torque Converter

    Here it is folks, what many said could not be done. For those keeping score, this marks the third breakthrough by Weistec Engineering (first being the M156 supercharger and second being CARB certification). The Mercedes 722.9 transmission is used in a variety of vehicles and made its debut in 2004. Tuners have struggled to upgrade it with some saying it was impossible due to electronic complications but parts are now available to take the transmission up to the 1000 pound-foot of torque handling range.

    The torque converter obviously does not apply to those with the MCT but the valve body, tcu, and other parts do. There will be more vehicles supported than just what is listed below.

    Here is what Weistec calls their Bullet Proof Transmission Upgrade:

    Click here to enlarge

    The transmission receives upgraded clutch packs, new gaskets and seals, filter, pump, and associated hardware. This also includes the valve body and TCU upgrade which can be purchased separately. Pricing? $5,489


    Key Features:
    • Increased Torque Capacity
    • Upgraded Clutch Packs Containing More Clutch Discs
    • Redesigned Clutch Piston Geometry
    • Increase Frictional Surface Area
    • Increased Clutch Material
    • Improved Heat Dissipation
    • New Gaskets and Filter
    • New Transmission Fluid Pump
    • New OEM Fasteners and Hardware
    • Fully Assembled and Ready to Run

    Supported Platforms

    Click here to enlarge



    722.9 Valve Body and TCU Upgrade


    This is the first and only valve body upgrade for the 722.9 transmission. This part improves the way the transmission shifts and increases line pressure. The changes in the TCU are made to compliment the hardware and make sure it all works correctly. With the increased pressure and software to compliment it this prevents the clutches from slipping. Turnaround time of 3 days, your parts must be used.

    Valve Body and TCU Upgrade priced at $1,478

    Key Features:
    • Increased Line Pressure
    • Faster Shifting
    • More Precise Shifting
    • Improved Transmission Lifespan
    • New Gaskets
    • New Filter
    • New Hardware

    722.9 Torque Converter


    This is the first and only upgraded torque converter for the 722.9 transmission. A lot of firsts coming from Weistec who continues to work their magic on Mercedes platforms.

    This does feature a higher stall of 2500 rpm which should help launches at the track considerably. Weistec stated that in their testing 60 foots dropped around two tenths which will have a large impact on a 1/4 mile elapsed time. It will also support over 1000 horsepower.

    Price is $2849.99

    Key Features:
    • Computer Designed
    • CNC Machined Billet Stator
    • 2500 RPM stall speed
    • +1000HP capable
    • Reduced 60 foot times
    • Improved Low Speed (Around Town) Driving
    • Maintains Factory Drivability

    So for about 10k you get a fully built transmission....sounds pretty reasonable to me for an AMG and the 3 day turnaround time is pretty impressive, too. Nice job Wesitec. Bet there are lots of guys out there who claimed to be able to tune the TCU who are scratching their heads right about now lol.

    GRAET stuff from Weistec.

    But come on, 3K for a TC. I had a custom one made back in the 80's from B&M for only 800 bucks. And it was certainly higher than 2500Click here to enlarge

    It seems that a couple of people plan on shipping their transmissions to Weistec for these upgrades. Is this the only option we have? Can't a competent transmission shop perform these upgrades? Can the torque converter be installed for those who are interested in a higher stall only and are not making the kind of power that Keith, Jim and Earl are making?

    My main interest is the torque converter for now. Eventually I would like to add the rest of the trans upgrades if/when I'm ready for a blower.

    Thanks in advance.

    As stated the valve body and TCU upgrade requires your hardware. You can probably just have the other parts installed.
