What is difference between a 1994 and 1998 DOHC transmission and are the valve bodies significantly different?

I'm pretty sure there is a difference in the solenoids, which are located in the valve body. I am also showing that the 1998 trans uses a different seperator plate then the 1994. I am also showing the 98 has a seperator gasket..... where the 1994 doesnt. just seeing different seperator plate numbers come up leads me to believe the entire valve body is different.
