Shifting into neutral

OMG... that means that if I'm sitting in my driveway and shift into neutral my transmission is going to blow up!

Well not really. Rear pumps haven't been used in most transmissions for more than 40 years.

As long as the engine is running, the front pump will lubricate the transmission.

I know one thing. If you bump a 79 Olds Cutlass with a console automatic into neutral while driving with the cruise engaged there was no safety switch to kick the cruise out. The tach was heading for outer space. I was proving a point to a factory rep at the time, so I was ready with the brake pedal. He couldn't believe it either. I don't remember if we were on a hill at the time. :)
Why in the hell would a legislature even be discussing a JaJa overdrive anyway? CA must be one weird place.

No on either.

A long time ago, I remember putting equipment in neutral on long straight downhills. Once the high-speed bounce passed, it was fun.

I don't know what your problem is. No one has suggested making a practice of coasting down hills in neutral. One person posted that if engine braking is giving you control problems in very slippery conditions, try putting the vehicle in neutral so the brakes can do their work without interference from the engine. You then start flaming them and calling people idiots.

There comes a point whenever we stop a vehicle that the engine stops providing braking and starts to try and push the car. It has to in order to keep from stalling. Normally we don't notice this with an automatic because the torque converter won't let the engine stall. The engine is still trying to push the car but the tires have enough traction to prevent it. This can be a problem when driving on ice in traffic. If it is a problem, put the car in neutral so the engine isn't interfering with the brake system. This is not rocket science, a person driving a manual does it every time they come to a stop. That is what a clutch does, disconnect the engine from the drive axles.

Bottom line, the only real idiot is the one that doesn't do whatever it takes to control their vehicle.

Here's food for thought. Anyone ever drive a straight shift and take too long shifting gears on the interstate? Or even miss a gear and were coasting in N? Press in the clutch to come to a stop? Or do you have perfect heel/toe action to perfectly match the rpm's on a downshift? I honestly don't see what the big deal is. If it was that dangerous, don't you think auto makers would make it impossible to shift into N while moving?

What you say about cruise and the ebrake is true but the principle is the same.

Front brakes wear faster because most front engine vehicles carry more weight up front and under braking, weight shifts off the back to the front. That's why front brakes are much larger than rears.

Unless the front of the car somehow comes detached from the rear, engine braking helps both sets of brakes. Both sets are stopping the same vehicle after all.

I'm not suggesting one should put a vehicle in neutral at speed but if you are trying to come to a stop on a downhill in very slippery conditions, you will not be able to do it in a RWD non ABS vehicle without locking the front brakes unless you put it in neutral. Those back wheels will keep on turning with the fronts locked or you will have to lock all four.

How exactly does engine braking help slow the front axle if not in 4WD?

Both my Dodges (2500 diesel 4x4 48re '03 and '07) the front and rear disks are the same size.

Did you not drive in winter up there back when just about everything was RWD or a clunky 4WD with front disks, drum rears, and no ABS? Did you spend eternity skidding?

Why am I wasting my time with this?

You aren't slowing the axle, you are slowing the vehicle. You can quit wasting my time any time you like.
