Procedure notes
The engine in your 2020 BMW M240i should be running when you perform a transmission fluid level check, otherwise it will be inaccurate. The video above shows where the transmission fluid dipstick or the transmission fluid check plug is located in your M240i and how to check the transmission fluid level. Your M240i will have either a transmission dipstick or a check or fill plug to perform a transmission fluid check. The transmission dipstick will typically be in the engine bay or on top or even the side of your M240i transmission. The transmission check plug will typically be on the bottom or the side of the transmission and may also be next to the axle. If the transmission fluid level in your M240i is low, you need to add transmission fluid through the dipstick tube or the check plug hole. When adding transmission fluid to your M240i, be sure to add it slowly as it will fill up quickly and is difficult to remove excess fluid if you overfill.
