hello,
i just recently purchased a MB 300E 1989 98K, doing maintance for last months by myself. I'm planning to change a transmission fluid (automatic) but after reading a manual got a little bit scared doing it (removing the pan and turning engine crankshaft), so i called a couple dealerships and the price they told me was 250-300$ (~170-200 for the labor). I have already bought a filter and a gasket (18$ both). The question i have is it a reasonable price, or its an easy DIY? Besides bleeding the old fluid, do i need to flush the transmission with any special stuff? Or maybe any other car shop is qualified enough to do it? And which ATF FLuid should i use?

the second question i have is about rear differential oil, i don't know i a previous owners ever replaced it (98.000 miles currently) and how important is it?

also i'm thinking of replacing two front engine mounts, because i have a little shakes/vibration on the idle, is there any way to check them?

the antenna mast is working fine but does not response to the control switch on the board (manual retract). also the standard Becker audio has a very weak reception, is it possible to install some sort of amplifier? and actually, i wouldn't mind replacing the original antenna with something shorter and just one solid piece, is such option possible?



thanks a lot for your answers,
andrei
