I got a killer deal on a used A440F Trany that was hand delivered to SnT for me. I am going to pull my clanking Trany and puth this one in. My rear main seal and oil pan both leak so those are being replaced. What other preventative maintinence should I be doing while the Trany is seperated from the TCase and removed from the vehicle? I don't want to spend more than one or two weekends so no major modifications or engine swaps, just the basic seals, gaskets, etc. Thanks.
