Eaton trans gasket kit
I ordered a gasket kit for an Eaton RTLO trans I'm rebuilding. ProGear had it in stock at a reasonable price. Shipping was prompt; I think it arrived in 2 days. My only complaint would be that the cost of shipping was higher that I would like. I'll be ordering more parts for them; it's simple and fast.
