Does coasting in neutral screw up your car?
yeah. does it? someone told me that it does, but i don't see how it could. is it better to downshift always? i heard coasting in neutral wears out your brakes faster. what do you guys say?

I don't see any reason that coasting in neutral could screw up your car. As for brakes, when you let off the gas, the engine will help slow your car down( even in an auto) , it helps save on brakes.

Re: Compression Braking Effect
Which is cheaper... brakes or engine Personally I'd prefer to wear out my brake pads rather than my engine. Coasting in neutral will do no damage to your vehicle.

When you coast with an auto tranny in neatral, you aren't driving the pump and are still turning gears, hense premature failure and burnt fluid! The trans pump in an auto runs off the shaft that turns the drive gears and if you are in neutral then the pump is sitting idle while other gears are turning and burning! A manual tranny needs no pump and just slashes the oil around even in neutral. Bill

The pump IS turning (and pumping) anytime the engine is running. (runs off the input shaft which is connected to the torque converter which is connected to the crankshaft) This is why you check the fluid with the tranny in neutral and the engine at idle. Check it with the engine off and it'll show "overfill" every time. Therefore coasting in neutral is not harmful in any way. If the engine is NOT running then you are absolutely correct. My original post simply stated that using the drivetrain to assist in slowing the vehicle instead of using just the brakes is placing more wear on the drivetrain. My original statement points out that brakes are cheaper than the rearend,tranny or engine. I'm making NO reccomendation here. Just pointing out something to think about.

Also your engine shouldnt have any problems if you do the downshifting thing (manual) as long as you have synchros to prevent crankshaft [shafting]
A simple doubleshift can keep even this from happening I believe

Actually you are supposed to check the auto trans fluid with the wheels
blocked and the car in gear. When the range selector is in neutral the fluid is not being moved inside of the transmission, therefore the car does not move. When the range selector is moved to a forward or reverse gear the pump turns and starts the fluid transfer throughout the transmission resulting in friction and therefore movement. When the rear wheels are turning the propellor shaft is turning (whether in gear or not) which turns the output shaft in the transmission and if the trans is not in gear then there is not fluid being pumped, this is why it is not a good idea to coast in neutral. Which brings me to this question, Why do you need to coast an automatic in nuetral? Downshifting an auto trans to slow down will not harm it though. Usually the electronic transmissions will not allow the engine to overrev by not downshifting until a certain rpm has been reached. Hope this helps

Coasting in neutral?
What up guys? I don't think coasting in neutral screws up the car. It's not the same for motorcycles; the clutch basket can be notched, besides ofr a motorcyle you need the engine turning to maintain that gyrospcopic effect. I coast to lights and stop signs all the time.... not s asingle problem has come up. My friend has a 2001 996 Twin Turbo... he also does the same.... he's been dricving Porsche cars for 15 years now..... not a single problem with his tranny.
I also have a 89 Dodge Daytona 2.5 normally aspirated car.. 100hp and 140 lb-ft of torque. It has a 3 speed automatic tranny.... as I tow two bikes on a 3 rail with luggage equipment for two adults, I coast to lights and through down hills all the time.... the car has 89K miles on the odometer. The car runs PERFECT! I once has a friend that had a C4 Vette... he shifted MANUALLY with his 4 speed automatic coupe (DUMB!)..... he traded the car in befor any problems came up... go figure? DRIVE SAFE! RK
