Modern car just start and drive, but go easy and don't drive like F1 until everything's warmed up (especially if turbo).

I believe your car manual will provide this guidance too.

If you notice, when start your car, RPM will be around 1500.
If you engage say Reverse, the RPM will immediately drop to around 1000.
I think the car does this to protect the transmission already.
So don't really need to wait till RPM drop to below 1000 to engage gear.

Hi everyone, just want ask.. is it true on morning need to warm up till the rpm drop below 1k for protect auto gearbox? especially for Perodua

give it a 10 second to lubricate all parts then start off soft can already till temperature reached the normal range before you start to drive/accelerate faster

Waste of time & petrol to wait up to 2 mins or more for oil to warm up. Modern engine just start & drive. I hv been doing for all cars and nothing spoilt other than wear and tear parts. If wait for warm up, how many years will you save yr car parts. Negligible. More important to change engine & gearbox oils regularly and stop worrying abt the rest. If it wants to break down, it will eventually and stop listening to grandmother story.

i didnt say you need to wait for 2 mnt, i said, start normally before u preparing to move ( select song, open gps whatsoever ) and thn drive slow and steady ( as for my car, i drive below 3k while coolant temp lower thn 70 ) after coolant reach 75, i drive as usual, vroom2 bebeh

Yes, you can start driving but need to highlight dont high rev. (control below 3k rpm) it as the cooling system and oil (both engine & transmission) not fully reach optimal working temperature. (oil need optimal temperature to work their best protection/performance)
If not fully reach and you keep up high rev. during cold start, your asking for high wear of your engine in short period.

Most modern vehicle controlled by ECU, cold start the RPM automatically higher for warming up purpose, most modern vehicle you no longer can see a water temperature gauge will only have blue or red etc indicator , cold start temperature water gauge temperature will have blue indicator as long disappear from your instrument cluster you are good to go less than a 2 minutes usually

If your still have water gauge meter is make sense reach the minimum temperature to drive

Either way as long within 2k RPM still safe to drive on cold start

Modern engine everything is so light and the engine oil nowadays is mostly design for start and go

Basically warm up minimum temperature only drive also a good practice if anything wrong with the engine on idle rather than half way faulty blocking the whole road.

You dont need to warm up the car. Just accelerate slowly and gradually as you exit the car park.

Bro, every oil got operating temperature including transmission fluid. If too cold it will also thicken up, slowing the oil flow (just imagine honey in low temperature). Installing addtional/aftermarket atf/cvt cooler without much research/data just increase the wear rate if you always drive in cold weather without proper warm up.
Before installing any of it check what is your normal ATF temperature like during like traffic jam, going up hill or fetching heavy stuff or trailer. Once you got the temperature data, check your original ATF gearbox spec. what is the optimal temperature range. Dont simply follow some mechanic or member peer pressure that all oil cooler must be good, a lot of time is waste money and more things to worry if done wrong (more hose, area to leak ATF oil)

High mileage car better wait atleast 15 secs for trans fluid to flow through valve body. Starts terus masuk gear may wear the clutch, kena gear slip then big regrets.

Ya understand now usually fuel injection no need warm too long. But the warm up for auto transmission gearbox.. I also confused want to wait or not..

Let's apply some logic here ya

You sit there warm up engine without moving, do you think the transmission gets to warm up too?

So if you want to warm up the gearbox, aren't you supposed to move the car?

i used to own an early 2000s perodua kelisa auto.

never have i warmed it up. i just start n drive. had the car for 7 years and over 100k km mileage on that car and never had any issues with gearbox or engine.

if a car that old can survive, cars these days have a better chance.

theres also an old saying

when the engine is cold, you cannot do this:
- in N (Neutral) tekan the accelerator to raise the RPM to 3k
- release footbrake
- engage D (Drive)
- this will warm up the auto gearbox immediately

Note:
- do the exact reverse to jaga gearbox upon first engagement, do slowly
- warming up the car does not warm up the auto gear or gear oil

The thing is, economy car equipped with cvt tend to drive better when cvt is warmed up, my experience with 2 diffrnt cvt car.
However, this doesn't mean u need to wait few mnt idling. just start, the car and drive slow n steady out of housing area and bla2, once the cold temp light is out / 2 ~ 3bar temp, drive as usual lor.

why all the confusion here?
