Transmission fluid change interval?
Thanks to the $100 coupon, just got my oil/filter changed at the local dealership.
As I'm coming up on 75,000 miles, while there, I asked about their recommendation on changing the transmission fluid and serpentine belt.
Supposedly my transmission fluid in the 2001 CLK320 is lifetime. However, I've read many forum postings that dispute this claim and I was told by the service adviser that MB has changed lifetime to 39,000 miles flush/change ($300).
To date, other then frequent oil/filter/coolant changes, the only repair needed was replacement of a MAF. Do most of the work myself or sometimes use an independent.
I would be interested in the groups wisdom regarding the suggested mileage for changing the transmission fluid and if a drain and replace would be OK (vs. flush and replace).
BTW, their reply on the belt was 'it depends'. I'm thinking that even it it shows no cracks, unusual wear and tear, it would better to replace it now (vs. risk breakdown).
Thanks in advance for comments.
