going fast or down long hills in neutral bad ?
this is really an 'ole wives tale' because when I was young
I was told not to go down long hills or go fast for long periods of time in neutral because 'something' is spinning that needs to be in gear.
Otherwise you risk some damage.
Is this true ?
I dont know if they were talking about the flywheel or what. I'm new to the workings of a car.
thanks

I heard this too, from what i think what spins is the syncrho (sp?) and when you try to go into a gear from neutral when your going fast (say 50 in neutral) and you put it in gear (lets say 2nd to slow down) thats putting alot of pressure on the syncrho, also waste alot of gas. Atleast thats how i always looked at it.

you would have to be retarded to put it into 2nd @ 50.
IF you have to slow down that bad you shouldnt of been
doing 50 in the first place.

first off....it doesn't effect anything inside the tranny in a negative way.
second....you have to be stupid to be cruising in neutral anyways- no control of car
third....rev match before shifting into gear and you'll be fine

I do it sometimes, I make sure to rev match though. I'm pretty **** about it, I rev match almost every gear for some reason for some fear that I'll destroy the synchros in my tranny if I don't get it perfect.

think before you talk.. how is it going to waste ANY gas when the car is in neutral? unless you have a habit of flooring the gas pedal when the car is in neutral you should be conserving gas.
Emerika is right though.. You dont have the ability to make a quick move when you're not in gear, but you could always rev-match before throwing it in gear if you dont want to risk hurting the tranny.

Re: going fast or down long hills in neutral bad ? (Honda.F1)
I blew an engine one time in my wifes Mercury (Zepher auto tranny) because I'd been coasting in neutral. It was more than 20 years ago. It was 105 degree's outside and my engine was running hot. We came to a long down hill running into a canyon so I poped it into neutral, something I commonly did in my 5 speed. My error was in not shutting off the cruise. When I got to the bottom of the hill I popped her back in drive. The cruise floored the engine because I had slowed down below the speed the cruise was set on. Before I could turn the key to shut the engine off it was blown. 200 CID Ford 6 cylinder couldn't handle a couple seconds of being floored. Be sure to shut off your cruise off before you do it.

it would never affect anything inside the tranny just crusing in neutral
dont you go in to neutral before changing gears at 50?

Believe it or not, coasting in neutral uses more fuel than coasting in gear; when you coast in gear, the engine shuts off the injectors so you are using no fuel whatsoever. When you're in neutral, the engine has to use some fuel to keep itself idling.
However it is not an unbelievably huge difference, I am just being a nit-picky jacknob.

Re: going fast or down long hills in neutral bad ? (Honda.F1)
being in nuetral isnt bad as long as the clutch pedal is depressed (foot off pedal)
being in lower gears (1st thru 3rd) while going downhill with the pedal pushed in is bad. clutch could be spinning upwards of 10,000 rpms and could fly apart destroying everything and flying thru your firewall into the passenger seat. do not do this. i have seen pics and now i keep the pedal depressed if im coasting, in nuetral.

Re: going fast or down long hills in neutral bad ?
The main reason I am asking this is because I want to conserve gas.
I understand the you have more control with it in gear.
thanks for the replies

You can't coast in gear , at least not for longer than a couple of seconds, it slows you down alot more than in neutral and I thought coasting in gear would be harder on your tranny. And coasting means driving roughly the same speed for a while doesnt it?

If the hill is steep enough to pull your car in gear without giving it more gas, the injectors are shut off by the ecu. This would make you save more gas than having the car in neutral which burns fuel. You are much better off in gear anyway for handling issues.

well if u actually go and calculate it. the amount of gas u would need to accelerate due to the car slowing down because you were in gear, may offset the amount saved in the first place.
good theory eh!

Re: going fast or down long hills in neutral bad ? (Honda.F1)
It is actually bad to coast in neutral cause the pump is not turning. An auto tranny uses atf to lube and pressure to change gears, the pump is run off the input shaft and if your car is in neutral nothings turning the pump which causes inadequate lubrication.

ah....the beauties of double-clutching. coasting in nuetral does nothing whatsoever to your motor or your tranny. although there is no reason to downshift into second while going fifty, it is very possible and very easily done. again, the beauties of a motor that can rev to 8000rpms safely.

Pull up next to me doing fifty and I'll shift to 2nd and walk you...you'll be so far back you'll be kicking yourself in the nuts
