I would like to service the transmission with new fluid and filter, how do you know how much fluid to put in and at what temp?? I saw a post for a certain temp but how do you know you have reached or exceeded that temp? Thanks for any help or personal experience you can give me to make this an easy diy project. :thumbup:

OK, so now my next question is - where are the engine designations listed. By context in other threads, I am guessing the M54 is a 6cyl.

Yes, M54 is the 3.0 liter 6. M62 and N62/N622TU are the 8 cylinder engines.

I've went through numerous post and cannot find a post with temp req when I replace my tranny oil. What I did was to drain the oil from the drain plug, then unscrew the transmission pan. replaced filter, seal, and put everything back. Then I just pump in oil until it leaks, and then turn on engine to wait for the oil to circulate, and then pump in more oil until it leaks consistently and screw it shut. Never pay attention to level or temp, been driving with no problem for 35K miles.

Very cool. Still under free maintenance but saved this in my favorites for when it expires :D

Thanks, I'll give it a try :thumbup:

Transmission temp should be between 30 and 50 degrees C. That is what is dictated by BMW for properly checking the fluid level. Checking the level also involves a bit more then just running the engine for it to circulate (i.e. A/C should be on, etc.)

How can I tell what the trans temp is? :dunno:

I don't know. I just answered the original question. The dealer knows the trans temp from the computer reading.

Buy a Infared temperature reader from pepboys for about 10 bucks, I believe.
