Should the oil level in an automatic gearbox be checked with the engine running or stopped?

Question

The dipstick shows a level for 80*C so I assume the oil must be hot before checking the level.

Answer 1

Yes, for an automatic transmission check the fluid with the car running, in park, with the car warmed up.

Answer 2

You should be parked on level ground, transmission in park or neutral, park brake on and engine running and transmission oil warm. Pull out dipstick and wipe clean, reinsert dipstick and then pull out again and check oil level indicated

Answer 3

Engine and transmission should be at operating temperature and run through all the gears. Then put the car in Neutral and apply the parking brake.. pull dipstick, wipe clean, fully reinsert and pull out to check fluid level.

Answer 4

Depends on the car, but normally it's the engine running and the autobox in park. Most dipsticks have two scales, one for cold and one for hot (IE 80*C).

Answer 5

Dear Friend, lift up u r car but straight, do not use crockdile jack. car should be straight. Add 1/2 ltr peugeot al4 gear oil & keep warming the gear box temp until 65 degree then remove the drain plug and leave the excess oil drain. ones all oil removed from the drain plug fix the bolt thats it. but i want to know which repair u have carried out in this g/b because u need to add 3.5 ltr oil if u replaced convertor seal.

Answer 6

Automatic transmission fluid is normally checked with the engine running.

Answer 7

Usually with the fluid warm & the engine running, but it does vary. You need to check the handbook or with a dealer.

Answer 8

as some of the other answer`ers will tell you, check it as specified in the particular manufacturers guide. Having established what the correct level is when that method is followed, wait till the system is cold (usualy the next day) and then see what the level is cold. Take note of the difference and you can then in future use either !

Answer 9

yes i needs to be 80*C check your owners manual in your car
most cars in the USA tell u to leave it runing when checking it

thats what i do all the time

good luck hope this helps

have good weekend and be safe

Answer 10

You can't answer that question without knowing what kind of car it is. Most cars you check idling in park, some in neutral, others you check with engine off.
