This is my first exhaust brake, and I didn't know what to expect. Questions for the gurus:

Should it make a loud air pssssssssssssst when it engages?

Does it put the transmission in a shift and lockup pattern similar to tow/haul? I noticed 4th gear lockup at 47 MPH, and the trans holds lockup longer and at lower speeds.

 

Yes and yes. Sounds like it's working right to me.

 

Thanks for the reply.

And I assume the braking effect increases on declines and with lower gearing, due to more force being applied on the pistons from gravity, momentum, and leverage? I was surprised at first when, on flats, it feels just like letting your foot off the throttle of a gasser.

 

higher RPMs met more braking hp. it takes a little getting used to, but once you are you sure notice when its not on.

sound like its right to me hiss can get anoying in town with the windows down on mine

 

On easy throttle...i.e. shifting at 1700-1800 in 1-2, 3rd should lock up about 30-32mph.
