Red Headed Stepchild-75 Swinger LSX Swap

Also having an issue with the trans brake. When it's engaged it's bogging the car down to the point that is stalls. Does it on first and reverse. Checking line pressure today, I filled the trans prior to dtno so I dont think fluid level would be an issue.

The trans brake manufacturer, Coan, advised me.to check line pressure and if thats good take readings across the solenoid. Which ahould be 6-8 amps. Which is what im betting on being the issue. So we qill get that figured put and tested this weekend seeing as I have to wait on my dash anyway.
