the car will downshift on its own (automatic transmission) usually on a hill.https://www.quora.com/Is-it-bad-for-my-engine-or-transmission-to-use-cruise-control-on-a-hilly-curvy-road
The advice here is definitely contradictory.
This is engine braking and it is normal.How normal is it?
Then, when i go down, the transmission keeps shifting down to use the engine braking to stop the car! this causes excessive wear on the transmission and is not recommended. It is much cheaper to buy brakes than it is to buy a new transmission (or get the few clutch assemblies in your automatic transmission replaced)Exactly - I just started "experimenting" with the cruise control - and sure enough I got the infamous Burnt Rubber Smell of clutch being destroyed. I have NEVER smelled this before!! I literally thought there must be a fire nearby - I smelled it twice. So I guess that's not TOO bad for driving almost 8 hours and in cruise control most of the time.
also cruise control is a great idea going down hills so you don't ruin or wear out the breaks prematurely. They will wear out really fast going down hills.Really? We've had the breaks replace in this car some five times - since I used to it to haul it full of fruit for a couple years.
But it's MUCH easier to get brakes replaced than for someone to try overhaul the extremely complicated and precise transmission system....
Cruise control use assumes that other drivers will automatically adjust their speed to avoid an accident. This is not a safe way to drive, as you are effectively outsourcing your safety.Yes I've noticed that people EXPECT you to slow down when they pass you. If the cruise control is on - people are gonna hit the car more likely! People do NOT use the recommended "three second rule" - which has been proven to cut accidents in HALF. oops.
https://www.quora.com/What-are-reasons-for-NOT-using-cruise-control
I keep it exactly at the limit and I don’t worry about the state trooper who hides somewhere between Pikeville and the 70 mph section of US70E.Admittedly - this is a VERY nice feature of cruise control - especially when a pesky cop is hoping your foot will slip on the gas pedal - as they follow behind.
Tailgaters will get up behind you and frustrate you. Tailgating can be dangerous, so if you're on cruise control, make sure you have a decent amount of stopping space between you and the car in front of you....Yep - cruise control really does not go well with all the tailgaters.
So those are two examples when NOT to use cruise control by whom?
Michael Stittman, Professional Automotive Technician .Trying to keep the motoring public safe and happy. Safe is the easy part.So that directly contradicts the person claiming cruise control is what?
"a great idea going down hills"oops!! No it's NOT because I got the burning rubber smell for sure - from up hills and down hills.

It [the speedometer] shows 70mph, but I think I am going much faster than this.”So the speedometer does not CORRECTLY report the cruise control speed! Fascinating (and deadly)....
Slipping Clutch - is burning rubber smell - from CRUISE CONTROL - youtube
Wow - I didn't know about that 1 to 1 ratio of acceleration and RPM increase for 4th gear (if 5th gear is overdrive)....
Breaking a clutch is not likely in just 5 seconds. Burning and overheating, yes. You’ve probably worn out a lot of the clutch material. If the clutch was already very worn, you might have worn it out enough to make it start slipping now.
To test for slipping, when you’re driving in one of the higher gears (4th, 5th) with clutch pedal not pressed, floor the accelerator. If the engine RPM rises suddenly without a corresponding increase in vehicle speed (mph) then your clutch is slipping and will need to be replaced.
No it's most common in Cruise Control!!Burning Smell
If you happen to notice your car emitting a burning smell, similar to burning rubber, then this is a sign that your clutch is overheating and your clutch plate is beginning to wear and tear. This is usually caused by riding the clutch and is most common in slow-moving traffic.
The clutch disc is slipping between the flywheel and the pressure plate, causing it to heat to the point of burning the fibrous clutch material.https://www.quora.com/What-does-a-burning-smell-from-the-vehicles-clutch-mean
So it was the pressure plate causing the problem. If this happens and you continue to rev the engine you will also get a smell. If you back off the accelerator and then press lightly on it you make get a bit more life out of your clutch.
having to creep up a hill [i.e. cruise control!!!!] in heavy traffic, the constant use of the clutch as you move away, creep a few metres then repeat, will overheat the friction plates and that smell is the result. similarly, if you are being a dick and try to wheelspin to show off, you can do the same.
You can put 10,000 miles of wear on a clutch in 5 mins if the car is drive incompetently or negligently.https://www.mistertransmission.com/best-ways-to-destroy-your-transmission/
https://www.quora.com/How-does-the-car-clutch-plate-burn8. Downshift to “brake” at traffic lights. [i.e. Cruise Control on Down Hill!!]
A forced downshift at high engine RPM is sure to cause excessive wear on transmission friction components (clutches and bands).
If the clutch is partially disengaged, we have both slip as well as contact pressure. This is the state when maximum heat as and hence loss of active material from the clutch disc takes place. This is the situation that is to be avoided.
If you [Cruise Control] cannot avoid slipping, due to slow moving traffic, do so with minimum heat generation. That is to slip with minimum contact pressure. This is possible only if slipping is restricted to the first gear. If you slip in higher gears, you slip with higher contact pressure and hence more heat and wear of clutch takes place.Worn Clutch versus Blown Clutch - vid of missing rubber burned off
If you engage the clutch very slowly, the relative slip between the friction plate and PP causes the clutch to heat up substantially. If you continue to do this, you are a very high risk of burning the clutch. Hence it is usually advised always start the vehicle using the 1st Gear.Maybe a brake caliper seized up? vid
But I'm pretty sure it was the cruise control!
