I don't have any transmission videos out for my builds but for over 20 years of building gm racing transmissions in the Cleveland area, I have never been able to help anyone understand all of your points since most guys already have their minds made up. Getting to work with Rossler, Abruzzi, and perfect converter along with picking local drag racing legend Al Goshling's brain has taught me all the tricks. 2nd gear start 400s have been around a long while but again most guys have always underestimated the th400 that even with simple upgrades like using an Ultra bell with 4L80e direct drum and wider bands with full manual valvebody can turn a basic 400 into well over 800hp range with a long lifespan for a street/stip vehicle. When you started with the first answer about difference between them is the overall COST! I had a good laugh since that is the same thing I always say when I get asked. GM engineers made the th400 into a true tank able to drive under land yachts and 1 ton trucks with bbc power in which a factory powerglide case would simply crack the case under such heavy loads. Will sub to channel for more good info. 👍
$7k-$8K for a built powerglide... When I swapped out the powerglide in my '68 camaro for a Muncie 4-speed in the early 90s, I couldn't give my powerglide away. Where was the internet when I needed it? ;)
If budget is no concern and you have the rear axle ratio capability to run out the back with no over drive, it’s hard to argue against a max build 400. The 400 has any aftermarket part you could image and are proven to hold up to 5000hp pro mods. Just be ready to get deep in your pocket if you want one for a 2000+hp 4x4 diesel for the swap is going to cost you between $30-35k

Good video..
Keep that content coming! We appreciate it!
Great video! You confirmed my choice in running a TH400 for my build. Great Content, keep the videos coming! Earned my sub.
Great video.
Thanks JP
Can you make a video showing how the 2 speed 400 works? What parts are used to make a 2 speed and what parts are left out.
What parts are you using to make a 2 speed th400 ?
Could you use a 1 speed power glide instead for lower hp applications?
Is a turbo 400 stronger than a max built 48re?😊
