I apologize in advance for introducing a topic which has probably been debated to death in the past. However, the time has come where I need to make a decision and would like some help. Our 1998 ML320 has just over 80,600 miles on the odometer. The transmission shifts correctly, hot or cold, and does not currently exhibit any problems. There is a shuddering when turning corners at low speed but I think this may be due to the transfer case issue with the early MLs rather than a transmission problem.

So, the question. Should I have the local dealer replace the transmission fluid and filter and incorporate the upgrades that have been outlined in the technical service bulletins? Should I just leave the exisiting fluid? I plan to keep the vehicle for several years with hopes of driving 200k plus miles.

I welcome your thoughts and advice.
