I am asking this just for outside confirmation, but I won't be able to make a throttle valve controlled transmission work with and electronically controlled throttle body and ECM, will I?

If I can't then I see two options.
1. buy a manual throttle body and install a TPS and IAC, problem with that is how will I get those attached to the ECM, and if that works I then have to pay to have my ECM tuned.
2. Buy the 4l60E transmission and use it instead of my 700r4.

To me it's kinda seeming like the cheaper route would be to buy a used 4l60E transmission and a driveshaft to hook up to my L59 5.3l and slap it in my camaro.

Any thoughts?

 

There is a way around that. You can get a constant pressure valve which eliminates a tv cable. Look up PATC trans or Hughes trans.
