How do I check/add ATF to my 07 bmw 335i E90 - BMW 3-Series (E90 E92) Forum

How do I add ATF to my 07 bmw 335i E90. I have a small leak from my transmission pan and its either from the sensor or the gasket and I dont have the spare money to just drop into it right now. The transmission is just starting to get a little rough when cold and I dont know how to even check, or add ATF to my car. If there is a video or walk through someone has a link I would love to see that if not some instructions would be great too.

Thank you

There are some great DIYs in the DIY forum.

Your leak could be from the sealing sleeve, its an area that a connector passes thru and it commonly fails and leaks.

Basically, to check atf level, the car must be up on jackstands or a lift, remove underbody panels, car must be perfectly level, remove the fill plug, make sure the atf in the tranny is in a certain specified range (car must be warmed up), top up until fluid flows out fill hole, close up and put her back together.

honestly i wouldn't risk driving it around with a leak. get it fixed.

new fluid has to be to spec, don't just buy something off the shelf.

these guys sell good stuff...
