torque converter

[BLACK SNAKE]

I feel my torque is slipping and I want to get a new one any suggestion on what brand to get. I am running over 400 hp. and 373 gears.

I've read some reviews and also looked at TCI being a very well reputable company.

I believe your transmission is a 4R70W?? I don't know the proper bolt pattern. Here is some info :

That is all I can find at this time. Maybe this will give you a head start on determining what is best at your application.

If you havent all ready done the J-mod, thats a must do. I cant imagine 400hp on the original ports. That in its self would raise hell with moving that power gear to gear and make much more heat in the trans oil.

If your not familiar with the J-mod, read this post. Its at the end of the article. These cars had the laziest shifts I ever drove in a car like this. The undersized trans valve body porting was a huge brain fart from the factor. The J-mod will make fast TC lock ups. No matter what TC you buy, if these ports are not opened up, you wont get the snappy shifts you want. With your set up, I would suggest the Rear differential mount support mod once you get the car shifting like it should.
