I religiously check and change ALL fluids
Borderline OCD
HA HA
here is a new question
Contemplating changing transmission fluid pan to a larger pan (extra 1.5 quarts) with a drain plug
Any suggestions on if that's worth it???
And how can I pull the old pan without getting covered in fluid??

I used the b&m pan for my 700r4 it was $50 or close to. It came with the filter extension and retainer spring for the filter. It is also nice because the inside of the pan is not chromed so you don't need to worry about that stuff flaking off inside your transmission unlike some of the other pans that are chromed inside and cost just as much with out an extension. FYI you can not run a deep pan with out the extension.
As for the benefits. Increased fluid capacity will prevent temperature extremes. It is much more difficult or in other words it takes longer to over heat larger quantities of fluid.
There is still no substitute for a good external transmission cooler hooked in line with the rad. In to the rad then through the cooler and back to the tranny. This way the rad gets the fluid up to temp and the cooler keeps it from getting to hot.
A cooler with a deep sump pan will greatly lengthen the life of a transmission barring other factors that contribute to transmission failure like super big tires with tall gearing or improperly adjusted TV cables etc....
When dropping the pan loosen all the bolts but do not remove the ones facing the front of vehicle. Remove all the other bolts and then slowly loosen the remaining side so that the pan slowly lowers and drains out the opposite side. Its still a crap shoot when it comes to making a mess. That's why even if you don't get a deep pan it is still nice to replace the stock one with one that has a drain bung. You could also install one in your stock pan on the cheap.
You can also get the pans in finned cast aluminum which will disperse heat on top of everything else. And if your really extreme you can get pans with tubes inserted in the bottom of the pans to allow air flow through.
On the flip side of all that you can get external transmission coolers with a mounted electric fan and temp sensor, which would really ensure that the heat is kept in check but they are pricy too.
