Quick question about measuring ATF level.
When I measure ATF fluid level, service CD says I should put transmission into "P", but doesn't say if I should shut down the engine or not.
I changed my transmission fluid by myself last week, now the car hums and vibrates when I stop the car with level in "D", I filled the ATF between min and max when engine temp was 80C, but I did that when the engine was shut down, don't if that was right or not.
Mine is a 92 400E, I use Mobil-1 ATF.
99 BMW 540i 6-speed 110K Km
03 SAAB 9-5 wagon 80K Km
92 400E (Sold) 245K km
Still missing the days with the Benz, it kept me busy.
