got a teeny weeny dribble from my gm180 kickdown cable at the box end, now its not attached to anything as its in my hotrod and not a rover. can i do away with the cable totally and plug off at the box? or am i best just putting a new O ring in and leaving it cable tied to the car chassis?

cheers

Why is the kickdown cable not attached?
It's needed to allow changes at the correct speed, dependent on throttle position, not just for kickdown.
 
The cable is fitted for a reason. If Rover/GM could have got away without fitting one and saved the money they would have done. The same applies to your other posting re the modulator. They both should be fitted and working.

The GM-180 automatic gearbox is a totally different beast to the Borg-Warner 35 and 65/66 gearboxes. Its up and down changes are controlled by its vacuum modulator valve, with assistance from a kick-down cable for rapid acceleration when needed. The GM-180 can be used with its kick-down cable disconnected, but the driver must use a certain amount of mechanical sympathy in doing so.

Also, the GM-180 gearbox will - if left for an extended period - leak from the right hand side and onto the exhaust downpipe. This is due to the contents of the torque converter draining into the gearbox sump, and leaking past the rubber boots of the dipstick tube orifice and kick-down cable orifice. I'm told this can be remedied to a certain extent, but never completely cured.

There is a more detailed explanation of the GM-180 gearbox over on the Rover SD1 forum if you want more info.
