We've had Redline MTL in the 77 240D's 4speed for the past couple years and 10k or so. I'm not sure exactly how long.
I've been so happy with it in my 242T that I flushed then changed the 240D to MTL right after we got it. Nice smooth shifts and a relatively quiet gearbox, considering the age and design.
