4L80E Conversion Question

[TheMonkey]

the car did not originally have any safety mechanism to prevent taking the car out of park without a key & press brake. i get super nervous about kids in the car when parked.



i'm doing the 4L80E swap.

is there any way to keep the 4L80E in P unless an electronic signal is sent? or... is a mechanical arrangement in the steer column necessary? somehow, it's electronic in my '05 Suburban because it requires foot on brake, but i'm not sure if the resistance is in the column or the tranny.

thanks,
Scott.
