I think my 727 is fried. Now I'm at a crossroads...

It’s possible, but considering how diligent I was being with monitoring the level, I’d say not likely.

I should have it out within a day or two, then I’ll post pictures of the snout. I’m curious to see what the seal and bushing look like as well.
Just a thought before removing the transmission. Remove the out put line from the cooler and see if you get a good flow. Maybe you have a restriction somewhere in that area. Sounds like somewhere you may have a plug.
