school me on the w56

[toyodaaddict]

i noticed that ther are like 5 models of the w56 trans. w56a,w56b ect. so do these all come outa 85-95 4cyl trucks? and how are they different? i have an 79 and an 84 toy both with the G52 trans,the one in the 79 just took a dump and i was planning on replacing it with a w56 but after seeing all the differant models im abit confused.

w-56 A 1985 all 22re motors
w-56 B 86-88 "                 "
w-56 C 89-91 "                 "
w-56 D  1992 "                 "
w-56 E 93-95 "                 "

After '88 "i think" the center section switch from cast iron to aluminim. I would go for a w56B

The A's center plate is aluminum.   The B's is iron.    Otherwise the A's and B's are the same.

(Don't know any details on the rest)
