I would recomment the 4L60E/4L65E trans
The 700R4 is not an electronic trans it has a mechanical kick down cable that will need to be hooked up to the throttle and you will need a governor that can shift at 7k rpm.
If you go with 4L60E trans here are the parts you will need.

Trans cooler & trans lines.
Electronic Control Unit (ECU) i use TCI Unit
Stock auto C4 L98/LT1 tailhousing.
Stock auto C4 L98/LT1 driveshaft
Stock auto C4 L98/LT1 C-beam
Either B&M or stock auto shifter.
Pricision Industries Torque Converter I worked with Pricision on the specs
just tell them you need a TC for LT5/ZR-1 and what stall you prefer
i recomment with lock up if you'll do street driving.
Flexplate (i have these) Just PM me.

If your going to run alot of power thru it let me suggest 4L80E trans
in this case it's alot of different parts.

If you have any questions feel free to PM me.
