Automatic Transmission Modulator Valve Replacement - W126 Mercedes 722.3

#impalamansgarage In this quick video I replace the transmission modulator valve in my Mercedes 300SD. Shifts from 1 through 3 are what I would call too aggressive and the the 3 to 4 shift is very harsh. I opted to simply replace the valve as opposed to trying to adjust the original part.
