You may also run into issues with your 03 base trans. Some 03's use the smaller cooler ports, and do not have the correct pump assembly for the g solenoid to function as that wasn't added until 04. Not sure what would happen if the g solenoid is commanded on without the correct hydraulic circuitry for it(but you could put a dummy solenoid in the pan to get around it).
If he is swapping in a 4th gen 6sp VB, IMS and harness into his built 03 trans to go along with the LBZ ECM, TCM, engine/top end and harnesses (like i did with my 04, save the trans which was a 2006 that i built), which is really the only way to do it, thats all a non-issue.

I wasn't sure about the different lockup boost valve. Up to 03 had the old style, 04+ has the one compatible with a g solenoid. It's been awhile since I looked at the hydraulic charts, and wasn't sure where the g solenoid would flow to when commanded on in an earlier trans with the different valve.
