Transmission Preventitive Maint on 2002 w210

[87path]

I have a question for everyone. I've been searching on what will need to be done when the time comes for changing the transmission fluid and have found these facts so far:

1. The w210 model I own is 2002, and will NOT have a torque converter plug to allow me to totally drain most of the fluid.

2. Without a torque converter plug, the best I can hope for is getting part of the fluid out by draining the tranny pan and diluting what's in there by adding new fluid.

3. One possibility for non-torque converter plug models is to flush the fluid by disconnecting the tranmission cooler lines and running the engine and re-adding fluid. However, this is messy and expensive since it requires a lot of MB tranny fluid.

4. General consensus is that tranny fluid should be changed between 45k-65k miles, unless you buy in to the "transmission for life" stuff.

My question, is if I just drain the tranny pan and replace filter on a regular basis, say every 10k miles, would I avoid having to do a major flush later on, since my car is relatively low mileage? I read that some people do this, although it's overkill, but my options are limited without a torque converter and it certainly wouldn't hurt!
