Default TT auto tranny swap

about to finally nut up and swap everything in. so just to make sure i have everything id like someone who has done the swap to go over this with me once more...... what i have right now tt auto tranny (boostlogic built) tt auto flex plate, built tt torque converter (lextreme is the shizznit), and of course the sc400 drive shaft. is there anything else?? i know there is some wiring required so also if any one has the diagram or can tell me what needs to go with what. also taking a look at the tranny the guy didnt include any type of electronics besides the plug ins directly connected to the transmission itself. thanks for any one that can help.

Eventually you will have a problem with SC400 driveshaft. Get a custom one if you can. The rubber couplers will get ripped apart and you might find yourself stranded.

I think I will just get a custom driveshaft. Looks like the SC400 driveshaft won't be able to push too much power anyway.

Yes, one is a transmission and the other is a diff. Repeat that question in a form that makes sense.

Hey Gazi. I swapped out the SC400 ds for the one-piece as sonn as I found the damaged couplers. The rubber couplers were fine until I put on some 285's in the rear

so i guess after hearing all that i will just wait and get a custom 1 piece drive shaft. on another note how well does the rest of our drive train hold up axles etc im finally about to get a tune on the car with the ems and the new fuel system. it has been a long and tempting break in period but im finally about to put the motor i built to good use. i just wanna make sure im not going to be killing my drive train when i do
