TH400 transmission

What's up people.. Does anyone know where or on what website to find specs for a TH400 transmission? I've heard of it being used in 4th Gen T/A's just trying to find out if it's a good transmission?why people use them? and i'm assuming it's and auto ( not sure)..any advice?

it's an auto, and it's a bulletproof transmission, but it's main downfall, and the reason you see more cars with a turbo 350 is because it takes more power away from your engine to run that tranny.

i've always been told, less than 400hp, stick with a turbo 350, more then 400hp, then it's o.k. to go either way cuz you won't notice that loss as much, on a rating scale, the turbo 350 is like a 8/10, and the turbo 400 is like a 10/10, just gives a power loss

i have the th400 and yes this transmission is unstopable...theres nothing you can do (well there is but) to break it apart i have a shift kit installed also with it and i have yet to have a problem with it.

Aren't the turbo 400's also three speeds?

yea the th-400 in my 76 is a 3 speed auto as well... shifs so nice with the shift kit

thanks for the info guy...Do you guys know if it can be used in 4th Gen T/A's ,came across and article from STS turbo systems of a project T/A they had, it said that it had a TH400 in it , just wonder if it's a common swap from a 4l60e to th400
