Why do I have a transmission relay?

I have the fuel pump relay on the firewall and next to it is a transmission kickdown relay. I have an 87 TBI truck with the 4.3L and a TH350 trans. I think (Not near the truck right now) the truck came with a TH350 new and I think that is what is in there now. It's either that or a TH350C.

I attached a pic I found on the internet to show what I am talking about.
