replacing tranny control module.. have question

well
I'm going to replace the control module on my A604 in hopes that it fixes my limp mode problem...

I just wanted to ask if there is anything that I should watch out for while I do it and if there are any specials steps I need to follow.

Also I picked up the front pump assmbly and the pump gasket... same questions there. special things I need to know when I replace these items.

Any help you guys can offer is greatly appreciated.

you might want to get it scanned to {really see what the problem is}
before you go through all that //// and not fix the problem !!!!
