    722.6 Bulletproof Transmission


    Availability: Out of stock


    722.6 Bulletproof Transmission

    Weistec Engineering is now offering an upgrade for the 722.6, 5-speed transmission used in many AMG and non AMG models . Every transmission is carefully disassembled and inspected to insure no fatigue to casing or other imperative parts. Once accepted we then cryogenically harden all gears, packs, input shaft, and output shaft.

    The transmission is then reassembled using our upgraded clutch packs, all new gaskets and seals, filter, and hardware. The Weistec Bullet Proof 722.6 is also outfitted with our upgraded Valve Body to ensure proper line pressure and superior shift quality. The result is a built transmission capable of handling power levels in excess of 1000lbft of torque while maintaining the drivability of a stock transmission.

    Note: Weistec Engineering thoroughly inspects the entire transmission upon arrival. During the build process it is important to understand that wear and tear items (such as clutches, seals, and gaskets) are replaced. Parts such as input shafts, output shafts, casing, etc. are not replaced in the build process. If there is damage to these parts a representative will notify the customer. Extra costs can be incurred if this is the case. Typical lead time is 3-4 weeks.

    Factory Mercedes transmission fluid required(filled per Mercedes Specified Procedure) upon installation.  Weistec Engineering strongly recommends re-adapting the transmission after installation to ensure proper operation.
