200k Mile Transmission: to service or not to service
So my trans is probably has all 200k original miles and it's getting old. I don't know if the previous owner changed filter or fluid and now it's acting up a little: Pendulum Shifting, poor gas mileage, drag.
Every once in a while I hear that if you change trans filter and fluid that hasn't been regularly changed, you run the risk of breaking loose some deposits on the inside. Is there any truth in that warning?
Should I just drive it until it the trans dies so I can do the auto manual swap?
I've personally seen it on a number of
ford and Lincoln's where they have high mileage without the fluid ever being changed, typically around 100k miles and the fluid is black, after changing it ,with 3 weeks the transmissions dies a painful death. I've never seen it on a bmw but i have also seen the same thing on the Isuzu rodeo's/troopers that share the same strassbourg transmission as the 525. Except they are a modified version for a transfer case. If a car have very high miles without a fluid change, i let the customer know of the possibilities and let them make the decision if they want me to change the fluid or not.
