Wondering if anyone knows if in the first year that chevy used the 700R4 which was 1983 did they also come with a lock up Converter back then also. Because i took a 700R4 off of a 1983 long bed truck but this truck had no computer in it so how is it that it had an 700R4 tranny in it. I also wanted to know if anyone knows how many wire's should come out of the Electronic plug located on the tranny. Thanks in advanvce junior 2-wheel'n all the way!!!
