I never even thought about the fact I can shift with my cruise control buttons! lol I was gonna hook up some paddle shifters just for the fun of it.
I will agree with the fact that there is more tuneability options with a EEC,, as it has the ability to read the actual LOAD on the engine based upon ACT, Temp, RPM, Mass-Air Etc etc..
While the TCS is strictly based upon RPM and TPS to get its load values.
But like I said above,, the majority of people who either swap in a EEC or TCS no matter what the application is probably looking for performace..
In a performance application either the EEC or TCS will do the exact same thing and that job is to actuate the solenoids at a given RPM. the shift solenoids or either On or OFF so there is no PWM to be concerned about, just the fact that you want it to happen within the engines powerband.
now with a AOD w/4r70w gearset you can probably get the shift points close but not without govenor or valvebody mods,, and it still leaves you with the inherant weakness's of the AOD design.
with the 4r70w you can tune to almost within 50 rpm of the shift point you desire,, if trying to acheieve every ounce of power out of your combo this is a great step forward. keeping the engine in its powerband is key.
Now personally,, I wish Baumann would get off his ass and work on getting the TCS to controll the 5 or 6spd automatic and be ablt to adapt them to the 5.0L platform.
