... Fluid MUST BE CHANGED EVERY 100K...
I was reading my OEM BMW X5 manual last night. There is an owners manual that talks about owner operation, it said the trans fluid is lifetime fluid (Marketing Statement to make you feel good).
It also has a maintenance BMW OEM manual,...
...that describes the maintenance items, It says that the ATF
MUST BE changed every 100,000 miles. Yes it does. Pg 3 of the Service and Warranty Information book for 2002 X5 3.0i, 4.4i, 4.6is So for the folks that say you are doing possible damage when you change fluid, what do you say to the BMW engineers that say IT MUST BE changed every 100K.
Direct quote from the maintenance manual.
"The following maintenance elements
must be performed at the mileage/time stated(time intervals start from the production date).
-Brake Fluid... 2 years
-Engine Coolant... 4 years
-Oxygen sensor... 100K
-Spark Plugs... 100K
-Automatic TransmissionService: Change ATF every 100,000 miles"
BOOM
