In my case it works very nice on highway and the overdrive + Gv Overdrive + LU cause to drop around 1000 rpm on normal or cruise driving not race, when i switch to manual mode i will able to control the gear vendor through from mastershift paddler shifter control system.

Damn, after looking at your build (and watching like 2 hours of Travel Channel), makes me want to go to Puerto Rico lol.

Have you used the Mastershift unit before? I read about it and another similar system, but I've never seen it used, since most of the guys with 6spd auto's will run the GM TuTd shifters. Does it allow for "full" control, or just the GV? (getting tap-shift for all 8 speeds would be epic)

i Have an Transgo HD2 modified valve bodies so when it put in D4 and switch to auto mode the tranny shift like factories does 4 + manual activation GV Overdrive , But when i ****ch to manual mode i have totally control over the tranny and GEAR VENDOR so there's when the master shift come on, the mastershift you can program it to gear splitting with the GV you will have 8 forward shift from your paddle shifter.
i have an another Modification in this tranny to handle the power from LSX 427 turbo.

1-Hardened Input Shaft
1-Hardened Hub.
1-TCI 2.97 First Gear Set
1-Intermediate Hardened Shaft
1-Alumum Direct clutch Assy.
1-Pump modification
1-34 elements Sprags
1-John Winter 3400 Stall 3 Clutch Lock Up Converter
1-red Alto Frictions
1-kolene friction plates
with this mods the tranny hold over 1400++ with out any issues

Looks like you kept the coil packs on the valve covers... Did you just custom make some plug wires andgo around the manifolds?

Yes, it's a custom make cables, because i'm using a Katech coil bracket set the OEM wire are to short to reach the spark plugs there're about 2" more longer than factories does, the wire set are Taylor 10.4 with ls coil ends.
