I think I get it now, I thought it was something to do with adjusting something in the trans. to improve performance. I read a post where someone used a jumper wire , but now that I think about it, that's an inexpensive way to get the trans. to lock up I believe. I don't need to worry about that. I guess it was a stupid question, but I just wanted to make sure I wasn't missing anything. Now for another "stupid question". What exactly does a Catcher do? I've seen them on alot of truck profile's. Will it work with my TST PM3. My truck is an '01, I think I had to do something to the ECM when I installed it, I can't remember. Thank's for any advice, and no chuckling if this is another stupid question! :-laf
