There are various configurations of pressure valves in the trans that control lockup function, you just want to have lockup in OD, and unlock on braking as a minimum. The BTO stuff makes eveything simple and right, but if you have the time to learn how it all works,how to fab and source the stuff you need, how to set it up right , etc. you don't need BTO. But they are a great choice for a hassle free installation and worth the money for me.

Awesome post thank you, I am looking to do just that.
In fact what I am looking to do in a bit is take a pic of the internal wiring on the valve body and figure out whether it is made from the factory to lock in 2/3/4, 3/4 or just 4. As mentioned trans was out of a 84 V8 Cadillac.
I am confident with the wiring and will probably just run the brake switch that I already have to pin A. The plug does have 3 wires on it from the donor car so I read that I might have to ground pin D as well. I like saving money instead of going BTO.
Also, I am thinking that a 700R4 TV cable will give me the perfect extra length
I am looking for and want to snag one out of a Camaro soon.
On the plus side, trans is in and fit up great!
