I was just reading through the DIY tips for the trans fluid change and I think this is probably a bit much for me. Anybody know what the dealer charges for this service? There is a good local import shop that worked on my old 300D that I'll probably take it to for some of the bigger stuff. I assume they'll be a little cheaper than the dealer for the trans fluid change as well.

Check the build date on your car, you might get lucky and have a TC drain plug. My car is a 2000 model year with a build date of July 1999, and I lucked out with the drain plug. They must have had leftover 722.6s from the '99 model year that got put into the first cars off the line for the 2000 model year. My indy got all the fluid out last month when I had it changed, which was a pleasant surprise. Otherwise I'd be doing the fluid change every 30,000 miles in order to account for only getting half out at a time. Now I'm going to stick with the 60,000 mile interval.
I usually point that out,same with other production date parts always confirm with prod date any parts that were specific to certain production times.
date is in the drivers door.

Thanks for the info...I'll check that out this afternoon.
110000 miles it is time,no sense in gambling.With the plug in the converter yours is a poc to drain so do it and all the old fluid will be gone.follow the diy and order all the parts before you do the job or find an indie that knows how to do the trans.

If you do not have a torque converter and you just keep dropping the pan and adding new oil that will eventually cycle all the old oil out correct? If you do this at least 3 times in different sessions right?
Practically speaking, you will never get all of the old oil out. I say practically, because as the oil is quantized (molecules), it is potentially possible to get it all out after a lot of changes. A WAG is more than just a few trillion times. Let me know when you're finished.
Assuming that you get half of the oil changed from the pan, changing it three times leaves about one-eighth old oil in the transmission.

Well, not really. Draining the pan gets about a third, so that becomes the benchmark. With that dilution your next drain and fill gets you to a little above 1/2, etc.
It is along the lines of the law of diminishing returns. That said, go ahead and do it, that's far better than ignoring it. Do the next pretty quickly, maybe just a few thousand miles, leave the pan on, just drain and fill. Do the same thing again for the next one and then keep them at perhaps 20,000 to 25,000 miles with a new filter at those.
That should get you pretty close, all the extra work and bother and shorter intervals is the reason behind all these tips and tricks.
88G280 I am with ohlord on this one, change that stuff out of there and the sooner the better. Take care and enjoy the ride,

Well i did do my first pan drop / filter gasket already at 79000 miles. Oil was very very brown ( glad i changed some of it). I did buy the shop tool dipstick to see if the amount in there was correct. I ran the car for a while to get the hot temperature reading of 80 celcius. everything seemed perfect for the hot temperature not to high not to little.
The next day i decided to pop off another red plastic cap to measure the cold temp reading. The car wasn't started all night. My car was parked all night on a slight ramped parking lot. I started the car for 1 minute just to reverse it and park it so that its elevated. Shut the car. I then took my dipstick tool and measured for the cold reading. and it was measuring above 25 celcius all the way up to half way mark.What could be the reason for this? The fact that i started the car for 1 minute? It was on parked on a slight ramp all night? Or too much fluid in trans?
The hot temp reading was perfect i was assuming the cold temp would measure accurate.
