There is a big difference in starting a manual trans in gear and starting an automatic trans w/o a NSS when in Drive.

The manual vehicle will immediately lurch forward. This immediately alerts anyone that there's something amiss. It is so obvious that only until recently (recently to me, anyway) vehicles w/a manual trans couldn't be started in gear w/the clutch engaged.

An AT on the other hand will not lurch forward. It will crank just as normally as if it was in Park. The surprise only comes when the engine lights.

Very true, there is a big difference.

I agree, but I'm guessing that the stock NSS is part of a column-shifted arrangement and the swapped trans uses a floor shifter. And yes, it's trivially easy to install an NSS, but how often have we done something for expediency with the intent to fix it later (and then never do...).

This is my car. It used to be on the collumn but is now on the floor. The NSS is still connected to the collumn and is not setup to work with the floor shifter so the car can be started in gear.

The only issue I've had with this was back when I was in tech school after basic training and my dad was driving the car down to Texas for me so I would have a car with my wife and daughter there. While driving down, dad could not get the car started after stopping for fuel. He had it towed and the regulator swapped out before the mechanic figured out the collar on the collumn was turned enough to open the NSS, preventing the ignition system from operating.

Other than that, there have been no issues. As far as children in the mix, whoop that little butt and make them mind on a daily basis. Teach 'em to not touch that which does not belong to them. Be certain they face repercussions when they do touch something that does not belong to them...even when no harm was done...teach them to respect the dangers of a garage and being around cars...be their parent, mentor, guidance counselor first and their friend second.

Funny you should mention this. Years ago I had the same situation on a car that I owned. I would manually rotate the collar to turn on the backup lights when in reverse. I would also rotate the collar all the way clockwise when I parked as an anti-theft device.

Thanks for posting. It's nice to know I'm not the only one.

I install a relay under the dash as a brake safety switch on old street rod. He could not crank the engine without applying the brakes first. That is because his tranny did not had a neutral safety switch. It saved his butt quite a few times because he did not realized he had the tranny in gear when he cranked the engine. The rod try to take off but since he had the brakes applied it did'nt take off. He could of run over somebody if he I did not had the brake safety relay installed.
