    W4B 040 racing transmission on 500E?

    Has anyone tried to install or knows about a “racing transmission” W4B 040, 4-speed automatic specially developed by Mercedes Benz for 500 SLC/560 GE on a 500E?
    Interior of the gearbox is made by “gold” meaning Titan, etc etc which is very expensive.

    To my understanding from searching around, is the W4B... the early generation 4-speed 722.1 w/torque converter used on the 4-5-6 inline engines. Due to the higher torque the early V8 powered models used the 3-speed W3A/B... while the M119 V8s uses the W4A040

    I've never heard of a W4B040 fitted on a M119, but I can easily understand that a 4 speed was developed for the known 450 SLC rally cars:
