Default 700r4

Do the serial numbers indicate the year and model it came out of.

There were approximately 250 changes between 1984 and 1993.
Some minor, some major. There were also many different calibration changes due to the vehicle it was going in. Do your homework before buying. Search this forum. There are many helpful posts in the archives.

Thanks Pete, I just found one of the posts. I should have looked harder/smarter. I think for the money, I'll buy it for no other reason than to see what I am getting myself into when I pull mine.
