Thank you for the fast reply.

I drove the car a bit to get the trans up to temp, lifted it level, and added a full quart of the blue bottle Trans-x. About 1/2 quart went in before anything overflowed, I suspect that means that the trans was approx 1/2 quart low.

There is some leakage on the outside of the trans, I didn't get a good look as to where it is leaking from. I sprayed some good PB 80 penetrating oil on the pan bolts, so in a week or so when my filter and gasket arrive from Pelican, hopefully all bolts cooperate and come off easy.

My plan now is to drive it easy a bit, 100 miles or so, then drain and fill once about 3.5 -4 quarts seems to be the general belief of what comes out when you remove the drain plug. Then, after the filter kit arrives, I'll remove the pan, change the filter and add another bottle of trans-x blue bottle and fill the rest with new OEM ATF 1 fluid.

Does everyone agree with this, or if not, have suggestions and reasoning why some other course of action would be better?

The fluid is black and done, I'll see if the first 3-4 quart drain and fill improves or degrades the behavior of the trans shifting and report back here.
