Speed hold solenoid and anti creep switch

Speed hold solenoid and anti creep switch
both of these have be electrically disconnected on the car by who ever owned it. anti creep seems redundant to me as modern cars don't go there. creep switch is very old and probably does not function (as most of them don't). can the speed hold solenoid be removed and a plate and gasket be used to seal the opening? should the switch be replaced with new brake line splice?

Extra splice in brake line is not advisable. Might not pass inspection in some states. Anti-creep switches are fixable, and the anti creep solenoid makes holding the automatic car easier to hold and keeps steady on hills. The older auto transfers torque quicker, compared to the new cars which have computerized transmissions which decide for you. Do what you want, but splicing brake lines, I don't recommend, kind of like splices in electric lines in the home.

JagStuart the speed hold is the more useful of the two. That box (even properly adjusted) will shift a bit too soon into direct drive. Depending on your driving habits you might consider returning it to functioning. It allows the car to be "sporty" and will remove the requirement to keep your foot in it to prevent premature shift.
As to the hill hold or anti-creep it is an interesting and sometimes useful function. Making it work is not difficult. Your decision but if you do return it to function here is one word of caution. When working on a running car always have the car in park or if in a gear make sure the park brake is on and functioning. More than one car has been launched into a wall while being serviced. When in gear with the hold engaged it is easy to exit the car and assume it is in park. At that point if working on tune for example a blip of the throttle from under the bonnet releases the hold---then all you can do is watch!
Best of luck.

My car still has the speed-hold solenoid and I would definitely want to keep it. Indeed, I just paid a large sum to GW Autos to fix it! In any event, I'm not sure whether it would be feasible to remove it and blank it off.
My anti-creep switch is still in place on the gearbox, and indeed was replaced at the same time as above, to reduce leakage, but is disconnected electrically and the solenoid is bypassed by a new brake line.
