Edit: After looking at the cost of the trans module and the bellhousing adapter, I realize that my price suggestion probably isn't reasonable.

and will the TAP shift work with the conversion
Shifter Posistions: P, R, N, M
That means manual mode for DSC (Driver Shift Control) up (+) and down (-) or an "L" gear (like in the Buick Enclave) where the driver can set the highest gear the transmission will use:
wvuguy, hope I'm not stating the obvious to you, but note that the "manual" mode on the Enclave is different than many (most?) other cars. It does not let you set what gear you want to be in, but rather sets the highest gear the trans will use, but it will freely use lower gears.
For those without paddle shifters, there is an option:
Shifter from an unknown newer GM vehicle used in a 2007 TrailBlazer RS with the 6L80E:

I can't speak for anyone else, but if a complete swap package with all of the components you listed above could be had for $800-$1000 or less, I think this becomes the standard upgrade for anyone looking for better performance, or, more likely, replacing a failing 4T65.

As for the module, that PCS module on that website doesn't talk to the T43.
Everything minus the transmission and the install I figure ~$1,000-$1,100 sounds reasonable.

Update:
Confirmed a bell housing adapter plate is not needed. In it's place is the 6T70 bell housing. It will successfully bolt to an LS4 and a 6T75.
We're looking at the following kit:
-6T75 adapter bell housing, machined for the starter's access
-Starter mounting bracket, polished steel
-Poly bottom side brace, polished steel
-Programmed ECU and hand held tuner
-Half shafts (still working on finding specs and adaptability)
Less the half shafts, were looking at around $1200.
Still an interest?

Just an FYI, some of the other cool projects were working on:
World's fastest 2.8L 12V Audi A4 Quattro - Projected completion -End of 2011
The 12V 2.8L was only for 1996, therefore a performance market was never established. The kraut's love for the 1.8T drowns out the 2.8L's displacement potential. It being 10:5:1 compression shoots down boost ideology. Superchargers were sold years ago for 7K and increase HP by about 110WHP, bringing finished product to around 280-300WHP.
In the works is a 3.5L 9:1 stroker kit, producing closer to 350WHP, with a boost acceptable bottom end.
Get this, the world's fastest 12V A4 has never been recorded. The fastest B5 A4/S4 that I've heard of is a mid 10 sec car. I'm shooting to chase down both records, in full trim. In addition, I am shooting for a road race capability in case the record breaking gets to bland. Chassis has 200,000 miles on it, and weighs in at 2992lbs.
Project: Violent - Projected Completion - 2012
80mm single turbo 355 + 2 stages of bottle fed + <2000lb. curb weight = Violent
Thanks for your support!

I spoke with Jesse at True Blue. We compiled ideas for a few and came to a couple of conclusions. As it stands, there are a few roadblocks on the ECU and TCM. Using EFI live for tuning is a definite necessity we both agree on, but isn't a total solution.
The problems are:
1. The program for the factory trans. is set for a sparse amount of engine types, i.e. ecotechs
2. We would need an aftermarket ECM
3. Programming the 6T would require accessing the trans. programs and matching the links with the donor vehicles ECU, ECM, etc. We would need to access the programs via EFI live and through Delco's access limits. A dealer would more than likely be needed to help us gain access.
4. We would need to match the links and run multiple programs and fight a good amount of trial and error before the bugs are worked out.
5. A harness adapter would need to be incorporated, Current Performance Wiring would need to be consulted for the project.
I'll do my best to get some answers and solutions, however this will put us way above budget for an affordable kit.
Hit me up with some ideas on it still being worth while. I want to help the community, but don't want to market an ill thought project.

I've spoke with TCI, they want an outrageous amount to make any units for the application. Something around 6-7K for R&D. I've got a good programmer with AcDelco here in FL locating some files and solutions.
We'll have to wait and see what he comes up with. I'm all set for making the bell housing and starter bracket work, however would like the other issues to be clarified before I market the machined parts. A lot of times, large companies like TCI will buy the parts I make and add the programs and sell the kit. I'd like to keep this affordable enough for our community and not have a need to deal with severe inflation.
