700r4 in a pre ecm vehichle

Could a 700r4 be run in a pre ECM (non computer controlled) vehichle, and would it still shift properly and go into overdrive?

You would still need a TV Cable and some way to lock up the converter (I'm using a TCI Vacuum lockup kit).

The TCI vacuum kit is nothing more than what GM used in the carbed vans and trucks.

It was used on the Canadian carbed F-bodies which were not CC'd either. My 84 has one.

Option 1: Run a non-lockup converter and converter the trans accordingly (very easy).

Option 2: TCI vaccum lockup kit

Option 3: Electronic lockup system, check the tech section on TGO, it will show you how to build one for very little money

Option 4: Hydraulic lockup kit
