Well the thing is; people do not expect a jerky transmission problem in a S350 which costs close to $90,000.
My 12 years old Saturn never had transmission problem.
My Toyota had a buttery smooth transmission.
My Chevy Malibu had a smoth transmission plus and handled better for the 8 years I had it.
My Chrysler's transmission dos not jerk, and this transmission was originally designed in 1999 or so
Now I expect that my $75k luxury vehicle should atleast
be as reliable as a 12 years old Saturn. Is this too much to expect ?
You might be enjoying your jerky transmission but I am too embarrassed to let one of my friend drive my jerky luxury
I understand where you're coming from. The problem here is not only the failure of performance expectancy, but the club in the wheel factor that exacerbated, if not created the transmission problems.
1) Whose fault was not to replace filter and gasket, plus pan and magnet cleanup, when flushing the unit, I don't know.
2) How well and complete the ATF replacement was made, I don't know.
3) Whereas the transmission developed signs that thorough professional service and correct Star Tek diagnosis would have shown earlier, or at servicing, I don't know.
What I do know is that these mystery failures appeared shortly after transmission service at an MB dealer or approved shop. There might be some shared negligence: on the one hand to save service/repair money; on the other, the abuse of mercenary service technicians, clerks and owners of the 21st century. You are right, you should not expect what you're getting, but is par for the course (examples galore the world over).
Your only choices, become proficient to dictate and check what you get done; or silence of the lambs and pay, since it's only money. But, not to loose face you are left only with choice number one, or you need somebody able to advise you whom you'd trust blindly.
