Anyone running their Monty with Transmission Throttle Cable disconnected? I've tried setting it as stated in fsm but doesn't have much power unless I disconnect it.


You've potentially got other problems then.

Am I hurting the transmission by disconnecting it?


Absolutly Yes. This controls pressure on your clutch packs, and you will burn them out if you run it disconnected.

Is my problem elsewhere?
Yes

When adjusting cable, what increments should I use?
I'd do it exactly like the FSM says to. Check fluid levels exactly as the manual says to also.

It would help us if you filled out your signature, and told us what kind of vehicle we are diagnosing.

I hope you get it figured out soon.
