I'm pretty sure they don't recommend flushing. It can stir up junk and just cause problems. I think most people just drop the pan and change the filters and whatever fluid they can. I'll get around to mine one of these days.

Oh, one more question. Does anybody know exactly where the transmission range sensor is exactly? I get an intermintant code 0705 when the tranny won't shif out of first on occasion. I have read here that the sensor should be clean before possibly wasting money on he one.
I could really use some advise. Thanks.

If you have the 545RFE then it's a custom build! The CRD uses the "NAG1; W5J400 - W5A330; 5-Speed; Automatic Transmission" not the 545RFE. See the parts manual at http://www.wkjeeps.com/wk_brochures.htm#MANUALS. One giveaway is that CRDs don't have tow mode, if for no other reason than the W5J400 - or is it called the W5A300, I can't tell - doesn't have two 2nd gears (tow mode uses both). But then, it doesn't need it.

Indeed there is no dipstick, nor can you get one. I tried. The parts guy at the Jeep dealer has a Mercedes and he can't get one for his car either. He tells me some electronic device (he knew the name but I forget it) is attached somewhere to check the fluid level. So I am resigned to having somebody do xmission fluid changes for me. I'll be looking for an independent Mercedes specialist to hopefully save some money and yet get it done correctly.

Sorry I don't know what the transmission range sensor is, much less where it is. Does it sense power lines?

Flushing the trans is not with a chemical! It is more like bleeding the brakes... They pump new fluid in to the trans and they watch the color of the fluid leaving the trans. When the fluid coming out is the same color as the fluid going in, they stop. That's what is meant by a flush.

Not always true. Many shops, including dealers, do use a "transmission cleaner" solvent from the likes of BG (who of course claims it cures all that ails you and that the transmission is full of filth that needs to be cleaned out with their product).

Don't assume. Ask.

Indeed you should have the W5J400 trans fitted to your CRD.
Trans level has to be measured when at a certain temperature , on the W5J400 the correct level is 68mm when fluid temp is 140 degrees F.You will need some means of measuring the temp correctly when the engine is running and the gear selector is moved through Drive/ Reverse /Park several times ,i use a Dashhawk and when temp reaches 140 F i check the level with a long welding rod and measure the amount of oil on the end of the rod with a engineers rule.
I have changed my fluid and filter several times using this method with no issues.

My dealer said not to flush, I checked the dipstick and it was bright red still so I am thinking it was done. I'm waiting till next spring as it looks like a mess to do (still deciding if I will weld a bung in the pan or buy the nicer heavy duty pan)...I'm leaning towards buying the heavy duty one.

Reason being with a bung welded in, the pan is not made to drain the fluid, so their be a ridge inside, thus not all the fluid or the junk that might settle get drained.

Tranny fluild and fliter change is very easy in my WK. I read the OP post and was like "Wtf?, i'd love for a dealer to tell me that. I'd be like is my 545RFE made out of titanium?"
