i'm doing a maintanence blitz on the 940 that I just bought, and a few questions are cropping up here and there as I read through the wonderful FAQ section here. I'm doing the transmission flush this afternoon, but as I've never done this before there are two things that aren't clear to me:
1. the FAQ instructions say to "Drain all the oil from the transmission drain pan (2-3.5 qts depending on model)." I assume this is out of the drain plug in the bottom of the transmission oil pan, a 14mm bolt. But after I drain it, and before going on to the rest of the flush, do I replace the bolt, like in a normal oil change? The instructions leave this step out...seems like it could be important! I'm guessing the answer is yes.
2. Once I remove the cooler line from the top of the radiator, do I need to plug up the cooler line, or does it just sit there, open, while I do the flush ?
the last, general question, is whether it is a bad idea to do this job before installing a new radiator, which I will be doing when it arrives in the mail. Does putting new AT fluid through an old radiator contaminate it?
thanks in advance for any advice!
