Check fluid level in transmision engine running or not with plug out

Its not simple, but can be done.Idle the engine for around 15 minutes to get transmission up to temperature. Lift the front of the car and remove the under tray. Locate a filler plug towards the lower edge of the valve body cover. While the engine is idling in Park remove the plug. If fluid runs out there is sufficient fluid. If no fluid runs out, add fluid through the filler until it runs out. This will leave the fluid at a minimum level, to get it to maximum level you must add another 700ml through the breather. Refit the filler plug, switch off the engine, remove the banjo fitting at the top of the cover, and add fluid through this hole. Check for leaks and refit under tray. Lower vehicle to ground

First thing to do is check your fluid level, which must be done with the engine running. If the level is low, fill to correct level and try again. If fluid level is ok, I suggest changing the trans filter. If that doesn't help, I suggest changing the transmission, or getting it rebuilt.

Underhood Check

Engine oil--Check the engine oil level.

Coolant--Check the radiator coolant level in the reservoir.

Battery-- Visually check battery cables and connections.

Automatic transmission--Check the fluid level.

Master cylinder--Check the fluid level.

Power Steering--Check the fluid level.

Windshield washer--Check the fluid level.

Belts & hoses--Visually check all belts and hoses for wear. NOTE: In addition to the items listed above there are cases with some manufacturer's where odd components such as manual transmission/transaxles and front differentials many be equipped with a dipstick found underhood for fluid level check. If you are unsure of a dipstick on your vehicle, check with the owners manual.

2005 Chevy Malibu has a sealed transmission with no dipstick, so you can't check the transmission fluid level without getting underneath the car and looking at the transmission itself.

Locate the transmission. Look for a small plug with a hex bolt on the passenger side of the transmission, adjacent to the passenger side front tire.

Start the engine and let it warm up to regular operating temperature. Remove the hex bolt from the plug hole in the side of the transmission with a wrench or socket. If transmission fluid flows freely from the hole, the fluid level is correct. If it barely drips, or no fluid comes out, the transmission fluid level is low.

Hi!!

Transmission hot,after been driven preferently, engine running, transmission in park. fluid level should be within the criscross area.

Good Luck!! Don't forget to rate this post!!

You do not need to check the fluid , the computer will let you know by means of the maintenance light if it is low.

Set the parking brake and put a block on at least one wheel. Pop the hood and find the Transmission dipstick. Start the engine and shift the gear shift into neutral. Pull the dipstick, wipe it with a clean rag, put it back in, pull it out and read it.

You didn't say which motor you have, but on my 3.6L, a plug is located on the RH side of the trans axle assembly. Just above the bottom tranny pan. Don't remove the plug when the engine is off or it will drain out ATF fluid. Start the engine and warm up to around 200 degrees. With the engine still running, remove the plug and fill to spill. When the level is right at the opening, reinstall the plug and you're done. I will attach a picture of this plug. Looks to be a 10mm.

The proper fluid level is marked on the dip stick. With the engine running and in park, raise the hood and remove the dip stick from the autotrans filler tube. With a clean rag, wipe down the stick and then place the dip stick all the way back in the tube again, and then pull it out once more.
Holding the stick level, you can now read what the fluid level is.

If you add any fluid, do so in small amounts, such as a half a pint at a time.

Do not add fluid with engine running.

If you have a automatic it's with engine at operating temperature, shift through all gears. Check fluid level in PARK and add fluid as needed.
