S 600 Sedan transmission problem
I bought this S600 nearly 4 years ago with 86000 miles on it. On rare occasions, the transmission would do a delayed down shift, hitting hard when the shift occurs. I think it was shifting from 3rd or 4th down to 2nd. It didn't happen but about once in 6 months. Other than this problem it is perfect in every way.
Now with 115,000 miles the problem has gotten worse. The 2-3 upshift is a little delayed and harsh. The down shift under full throttle at speeds over about 40 mph are real hard-the wheel spin light comes on momentarily.
I've had it to the MB dealer twice; they say that there are no codes being set; think the trouble is internal. Cost of them rebuilding is about $7000.00.
I talked with a couple of transmission shops and they wonder since this is the 5 speed computerised tansmission, that it may have a solenoid problem that is giving the problem.
Question; I hate the expense and if it is a small solenoid problem; why does the whole transmission have to be rebuilt when it has worked well for the last 4 years.
What do you think?
