4T65-E transaxle manifold pressure switch torque specs?

I'm getting ready to do a transaxle solenoid replacement job in a 2000 Buick Century. It's running an older 4T65-E with the bigger manifold pressure switch than whats found in the newer ones. I'm changing all the solenoids and this pressure switch, and I need to know the torque specs for it. All other sources I've tried looking into are just giving me the runaround so I'm hoping someone here can fill me in. Thanks!
