Default trans control module?

I'm sending my engine computer to magnuson for a tune. They told me to also send the trans control module. Where is this located? I know where the engine computer is...

It is in the pass side wheel well, but one module. It controls both the engine and transmission.

Thx ron, that's what I kept asking him and he insisted there were 2. I thought there was just the one also so thank you for confirming I'm not crazy!

I hope the guy on the phone isn't the one that does anything that matters. If he doesn't know this then I wouldn't want him programming my stuff.

1997-2004 uses a single PCM to control the engine and trans--
2005 and up uses two separte computers-one for the transs (ECM) and one for the trans (TCM)
