Transmission controller for exhaust brake

[CBari]

I have been wanting an exhaust brake for several years and am finally ready to pull the trigger on one. I have decieded on a pac brake exhaust brake, but because I have an auto I will need a transmission controller for the torque converter. Is there any reason why I should buy someone else's controller or just use the one that comes with the PAC brake.

i don't believe you need a additional trany cooler

love my PAC

I would use the Pac Brake one.

You will also need a BD Pressure Loc or all you will do is tear the transmission up.



Assuming you have a stock trans, you cannot drop an EB on there without making some mods or your effectiveness is going to be limited. At a minimum, you might want to look at a BD Towloc along with the pressure loc to actually make things live and work for a while. A shift kit is not a bad idea either.

I have a Goerend built trans Dave knew I was going to add an exhaust brake so I should be good to go

Then the Pressure Loc is all you really need.

CBari, you should use the Pacbrake transmission controller supplied in the exhaust brake kit. The Pacbrake controller has quite a few features built in to enhance the exhaust brake and to protect the transmission. The Pacbrake controller reads the vehicle network (Can-Bus) to ensure all the parameters are correct (cruise control, throttle position, vehicle speed, etc) before applying the exhaust brake. The Pacbrake controller forces torque converter lock-up sooner then the Chrysler program does to provide exhaust brake engagement at slower road speeds. The dash switch provided in the kit has an LED light in the end of the toggle, the light changes color to show the mode the system is in, brake ready is RED, torque converter locked up is GREEN and exhaust brake applied is an ORANGE light.

The Pacbrake controller also measures slippage within the transmission, if the controller detects slippage it will disengage the exhaust brake to protect the transmission.

It is my understanding that the "pressure lock" only increases oil pressure within the transmission, but doesn't control torque converter lock-up or have any of the other features of the Pacbrake controller.

Pacbrake's transmission controllers are designed specifically to enhance exhaust braking and ease of troubleshooting with the 3 color LED lights.
