750-1000+ HP drag racing auto transmission recommendations

Just like the title says, what are you guys running and why? Please include who built it, specs, HP capability, cost and any other info that you feel is important. I’m looking to go to the next level and would like some ideas of what direction to go. I’m looking to buy a complete transmission package from a specialty company like TCI .
It going to go in my SBF 89 hatchback. Thanks.

Anybody that drag races with an auto is gonna tell you to use one of two different transmission, and both are GM pieces.
a Glide or a TH 400.
A C4 is not up to the task, a C6 is a heavy pig that eats power.

It really depends on your use with the car . Drag car with none to minimal useage - power glide or turbo 400

street car that will do some real mileage - Freddy brown aod or a GM 4L80

For a mostly street, sometimes strip car @ that power level I'd use a 4R70W. Check "Silver Fox Racing". Put a U.S. shift controller on it. You will probably want a triple disc converter.
