Help with trans

Does anyone have a diagram of the automatic trans of a 93 front wheel drive 2.0 that shows the plugins in detail. The plugs are screwed up badly (one is missing) and the trans is down shifting from drive to 2nd. I'm shure this is a plug issue and if someone can help me find this info it would be a lot of help.
Thanks for your help.

Have you check the Haynes manual? I am not positive but i think i has it in there.
