Custom PIDs for 2004 Ford 6.8L V10 (2-valve)

I've recently downloaded the Torque Pro app for my Android phone to use in my MH. Engine is a 2004 Ford 6.8L V10 (2-valve). Because of the MH size and also towing a car, long or steep hills can be a challenge, so I'm trying to fine a Custom PID to monitor transmission fluid temp in Torque Pro. I've read that the Custom PIDs for trans temp that are provided with the app are for the 6.0L diesel. Can anyone provide or direct me to a source for a transmission fluid temp Custom PID for my motor? Thanks.
