Does anyone know 727specialist

anyone know about this guy. He said all he rebuild is 727 transmissions. I am thinking about sending him my 727 to rebuild. If anyone knows about his work. Let me know. Thanks
I may be wrong but I believe 727 specialist is the guy who took over Steve Griners business after Steves passing. He was schooled by Griner. He sells Griners brakes. But I may be mistaken.
But I agree you can do it yourself. I have done many successfully
after trying it for the first time.
