The 722.317 is a .3 trans & does have a six bolt pan, but the 17 in the 317 doesn't have anything to do with year & in most cases model of car! It is the MB definiton of the trans design, some versions can fit 3 or 4 different models. Other versions fit only 1 model. The two numbers are also part of the serial number & are needed when ordering parts. The trans 722.317 fits only US version cars. 1987 300DT(W124.133) & 300TDT(T124.193).
