Spending THOUSANDS of dollars on a TH400 that didn't last! Builder error and set up for failure. This unit will be about to handle close to 2000 hp when we get done installing all the SONNAX billet products. Just remember you can put the strongest parts available in this transmission, but if they aren't installed incorrect or if it's built incorrect we can have a failure just like any transmission. We hope you all enjoy and thanks for watching. ❤
