Dragsters and trans-brakes? (Page 1/1) psychosurfer JUN 08, 06:32 PM We race in a few classes, mostly nostalgia FC but also are running a super comp dragster. Does anyone know how to test a transbrake at the unit on the side of the trans to see if it is good? Ours is not working but I am thinking that it may be in my switches and relays. Just dont know where to start. Thanks for any input you can provide! -Scott
