What ratchet shifter are you using with a 518 46RE ?

Sorry guys, I modified my post after you read it.
If you change to a full manual valve body the RE can be used, but you still have to control OD and lockup manually if you don't run a shift computer.
Hey TrailBeast, if you get a chance watch this video. It's a megashifter in a 87 Trans Am with OD. There are no details about install but it lead me to believe I could do something similar. You'll see the ratchet accounts for 4 gears. But I bet an 87 was pre computer controlled trans.
