Recommendations for mail order transmission?

My 727 (340) is toast. Any recommendations for mail order companies?

Local places are not an option as i dont have the time to remove drop off and pick up amd reinstall
Looking to drop and replace in 1 day.

was talking to Rod Bloomer about my new heads couple days ago.
He asked if I knew anybody who needed a 727.
He has one with about 50 miles on it he had in a car he sold.
Some A&A parts in it, and turbo action reverse manual valve body. He said drop it in and go, zero issues.
1000 bucks.
