I am looking for an electronic speed sensor for a th400. I understand mostly these came in late 80s early 90s chevy trucks or vans.

 

FYI the 87 trucks with 3L80HD(new name for the 400 trans in '87 such as the LJA tag code ones) trans still had speedo cable, i owned one.

not sure what year had a 400 and vss the 400 was about done for, around 1991

possibly 88-91 had vss but i have forgotten hmmm
just worked on a truck in these years with a 400 also and i didnt notice if it was cable or vss equipped hmmmmm

 

Yes I understand some had cable and some were electronic, from what I understand the 3l80 (400) was between 88 and 91. Anyway now I am hunting for an electronic speedometer sensor for 700r4, 1990-91 I think I found a way to make it work if I find the right one.
