4l60e (1996 LT1) - How do I control it?

[Steve Chryssos]

I would like to keep the 4L60e and put it in a 70 nova. The Lt1 is not part of the set up. Is there a economical way to just contol transmission? Will a pcm control it without the motor? Everything I see is 500.00 would like to find something cheaper.

Thanks

If you will be putting the electronic transmission behind a carbureted engine then you you have no choice but to run a standalone tans computer. There is no inexpensive alternative. To the contrary, the cost goes up since you must add on some form of throttle position sensor or vacuum modulator conversion.
That computer is quite busy running shift and line pressure solenoids as well as handling other functions such as converter lock up and manumatic capability. The smart computers also factor in engine or trans coolant temperature to help extend transmission life. Sorry there is no cheap alternative, but I hope that I have helped explain WHY the stuff is expensive.
