While I wasn't able to get you the exact answer I can help you easily identify which transmission line is which on your truck.
1. Start engine while engine is cold
2. Place transmission shift lever in drive for no more than 10 seconds.
3. Stop engine and remove keys
4. Identify the oil return line by feeling both oil lines. The coolest line is the oil return line and the one to install the transmission cooler on.
