300 miles on new transmission. Fluid exploded out of filer tube. 4th gear gone.

First time I get on it only up to 15 pounds of boost and it felt like the transmisision dropped to first at 70 mph. Blew transmission fluid out of filler tube. Caught hoodliner on fire. Burnt hand. Let it cool off. Top off transmission and realize every time it hits 4th it feels like it's trying to go into reverse or engaging the new transbrake that was added? Even chirps tires when it drops to 4th or first or whatever it's doing. Drives normal other than 4th. Shifts fine. Any idea what could be happening?

Might wanna contact who ever built it. Was it anyone known for building the 200's?

Already talked to him. Going to pull it. Have no clue what happened. All we did was put new clutches in and a trans brake. Was built with all billet parts in 2009 and never had one problem with 40k miles on it.
